WARNING - STILL NO WORLD CHAMPIONSHIP CONTENT IN THIS POST
So let's walk you through how a tournament would work. We'll just do this for the top division - lower divisions, for all intents and purposes, operate in the same way. Let's start with the ranking list as of the last tournament - here I've just taken today's FRH rankings and placed players accordingly:
To demonstrate what happens in the event of someone not taking part, I'm going to pretend Gary Anderson and Ryan Joyce have withdrawn from this event. I'm just maintaining the standard ranking names as used in sumo, which would clearly be anglicised somehow, but from here, let's draw the first two day's matches and simulate it:
Day 1:
Luke Littler 0-2 Jonny Clayton
Luke Humphries 0-2 Michael van Gerwen
James Wade 0-2 Nathan Aspinall
Gian van Veen 1-3 Chris Dobey
Danny Noppert 5-3 Josh Rock
Stephen Bunting 5-3 Damon Heta
Gerwyn Price 3-1 Ryan Searle
Jermaine Wattimena 3-1 Luke Woodhouse
Ross Smith 3-1 Mike de Decker
Martin Schindler 3-1 Cameron Menzies
Wessel Nijman 3-1 Dave Chisnall
Daryl Gurney 3-5 Andrew Gilding
Dirk van Duijvenbode 2-0 Ricardo Pietreczko
Rob Cross 0-2 Ritchie Edhouse
Peter Wright 1-3 Michael Smith
Joe Cullen 2-0 Dimitri van den Bergh
Krzysztof Ratajski 4-2 Martin Lukeman
Raymond van Barneveld 4-6 Kevin Doets (j)
Willie O'Connor 2-0 Niels Zonneveld
Niko Springer 0-2 Scott Williams (j)
Day 2:
Luke Littler 2-0 Martin Schindler
Luke Humphries 0-2 Stephen Bunting
James Wade 2-0 Jermaine Wattimena
Gian van Veen 3-1 Wessel Nijman
Danny Noppert 1-3 Gerwyn Price
Jonny Clayton 0-2 Dirk van Duijvenbode
Michael van Gerwen 2-0 Peter Wright
Josh Rock 2-0 Daryl Gurney
Nathan Aspinall 3-1 Chris Dobey
Ross Smith 6-5 Damon Heta
Mike de Decker 4-2 Ryan Searle
Luke Woodhouse 3-5 Nike Springer
Cameron Menzies 2-0 Raymond van Barneveld
Dave Chisnall 0-2 Krzysztof Ratajski
Rob Cross 2-0 Andrew Gilding
Ricardo Pietreczko 1-3 Joe Cullen
Ritchie Edhouse 0-2 Willie O'Connor
Michael Smith 2-0 Dimitri van den Betgh
Martin Lukeman 2-0 Callan Rydz (j)
Niels Zonneveld 2-0 Brendan Dolan (j)
These are all ordered with the highest ranked player first, and the higher ranked player on the left. You'll notice that most players will have one match on each side of the match list, this will indicate that they've played both someone ranked higher and lower than them. Obviously those right at the top (and bottom) can't do this, and for some other players it can't be helped to give them an easier/harder start, but we can rectify that as we start to schedule based on record as well. Looks like there's only eight players with a 2-0 record already. Those players I have denoted with a (j) have been called up from the division below for that day. The first two days were decided mostly at random, but I'll start scheduling with a bit more thought from now on.
Day 3:
Luke Littler 3-1 Gerwyn Price
Luke Humphries 3-1 Nathan Aspinall
James Wade 0-2 Jonny Clayton
Gian van Veen 4-2 Michael van Gerwen
Danny Noppert 1-3 Chris Dobey
Stephen Bunting 2-0 Ross Smith
Josh Rock 4-2 Mike de Decker
Jermaine Wattimena 2-0 Martin Schindler
Damon Heta 4-2 Rob Cross
Wessel Nijman 3-1 Cameron Menzies
Ryan Searle 5-3 Luke Woodhouse
Daryl Gurney 0-2 Dirk van Duijvenbode
Dave Chisnall 4-2 Michael Smith
Peter Wright 0-2 Willie O'Connor
Andrew Gilding 2-0 Ritchie Edhouse
Ricardo Pietreczko 0-2 Mickey Mansell (j)
Joe Cullen 0-2 Krzysztof Ratajski
Raymond van Barneveld 1-3 Niko Springer
Dimitri van den Bergh 1-3 Ricky Evans (j)
Martin Lukeman 0-2 Niels Zonneveld
This has now resulted in quite a lot of the undefeated players lose today - only Bunting, van Duijvenbode, Ratajski and O'Connor remain with perfect records. Let's keep going on.
Day 4:
Luke Littler (2-1) 0-2 Gian van Veen (2-1)
Luke Humphries (1-2) 2-0 Jonny Clayton (2-1)
James Wade (1-2) 0-2 Josh Rock (2-1)
Danny Noppert (1-2) 5-6 Michael van Gerwen (2-1)
Stephen Bunting (3-0) 6-4 Gerwyn Price (2-1)
Nathan Aspinall (2-1) 0-2 Jermaine Wattimena (2-1)
Chris Dobey (2-1) 0-2 Dirk van Duijvenbode (3-0)
Ross Smith (2-1) 2-0 Martin Schindler (1-2)
Damon Heta (1-2) 3-1 Mike de Decker (1-2)
Wessel Nijman (2-1) 2-0 Ryan Searle (1-2)
Luke Woodhouse (0-3) 0-2 Andrew Gilding (2-1)
Daryl Gurney (0-3) 0-2 Krzysztof Ratajski (3-0)
Cameron Menzies (1-2) 3-1 Willie O'Connor (3-0)
Dave Chisnall (1-2) 6-4 Rob Cross (1-2)
Peter Wright (0-3) 4-2 Jeffrey de Graaf (j)
Ricardo Pietreczko (0-3) 0-2 Ritchie Edhouse (1-2)
Joe Cullen (2-1) 4-2 Michael Smith (2-1)
Raymond van Barneveld (0-3) 2-0 Martin Lukeman (1-2)
Dimitri van den Bergh (0-3) 2-0 Niels Zonneveld (2-1)
Niko Springer (2-1) 3-5 Kevin Doets (j)
So we see Bunting, DvD and Ratajski maintain their perfect record (and lock up winning records) but Ratajski falls off into a big cluster of nine players at 3-1. At the other end three players have now dropped to 0-4. We go again.
Day 5:
Luke Littler (2-2) 2-0 Danny Noppert (1-3)
Luke Humphries (2-2) 1-3 Gerwyn Price (2-2)
James Wade (1-3) 4-2 Gian van Veen (3-1)
Stephen Bunting (4-0) 2-0 Michael van Gerwen (3-1)
Jonny Clayton (2-2) 6-5 Wessel Nijman (3-1)
Josh Rock (3-1) 3-1 Jermaine Wattimena (3-1)
Nathan Aspinall (2-2) 6-5 Ross Smith (3-1)
Chris Dobey (2-2) 0-2 Krzysztof Ratajski (4-0)
Martin Schindler (1-3) 3-1 Mike de Decker (1-3)
Damon Heta (2-2) 2-0 Dirk van Duijvenbode (4-0)
Ryan Searle (1-3) 1-3 Willie O'Connor (3-1)
Luke Woodhouse (0-4) 3-1 Daryl Gurney (0-4)
Cameron Menzies (2-2) 1-3 Dave Chisnall (2-2)
Rob Cross (1-3) 2-0 Peter Wright (1-3)
Andrew Gilding (3-1) 0-2 Joe Cullen (3-1)
Ricardo Pietreczko (0-4) 2-4 Dimitri van den Bergh (1-3)
Ritchie Edhouse (2-2) 5-3 Callan Ryfz (j)
Michael Smith (2-2) 3-1 Scott Williams (j)
Raymond van Barneveld (1-3) 2-0 Niels Zonneveld (2-2)
Martin Lukeman (1-3) 3-1 Niko Springer (2-2)
So Bunting and Ratajski remain unbeaten, and will be given legitimate opponents, while a lot of players have now secured a winning or losing record. Let's go on.
Day 6:
Luke Littler (3-2) 1-3 Stephen Bunting (5-0)
Luke Humphries (2-3) 2-0 James Wade (2-3)
Gian van Veen (3-2) 3-5 Gerwyn Price (3-2)
Danny Noppert (1-4) 5-6 Krzysztof Ratajski (5-0)
Jonny Clayton (3-2) 2-0 Josh Rock (4-1)
Michael van Gerwen (3-2) 2-0 Nathan Aspinall (3-2)
Chris Dobey (2-3) 0-2 Willie O'Connor (4-1)
Jermaine Wattimena (3-2) 6-5 Dirk van Duijvenbode (4-1)
Ross Smith (3-2) 2-4 Cameron Menzies (2-3)
Martin Schindler (2-3) 1-3 Damon Heta (3-2)
Mike de Decker (1-4) 0-2 Joe Cullen (4-1)
Wessel Nijman (3-2) 3-1 Dave Chisnall (3-2)
Ryan Searle (1-4) 6-4 Brendan Dolan (j)
Luke Woodhouse (1-4) 2-0 Peter Wright (1-4)
Daryl Gurney (0-5) 0-2 Ricky Evans (j)
Rob Cross (2-3) 0-2 Niko Springer (2-3)
Andrew Gilding (3-2) 3-5 Michael Smith (3-2)
Ricardo Pietreczko (0-5) 2-0 Raymond van Barneveld (2-3)
Ritchie Edhouse (3-2) 0-2 Niels Zonneveld (2-3)
Dimitri van den Bergh (2-3) 2-0 Martin Lukeman (2-3)
So going into the final day, we have two undefeated players, who'll go against each other for the title. This is also where we chuck as many players on 3-3 against each other as possible to see who ends up with a winning record, which oddly includes both Lukes.
Day 7:
Luke Littler (3-3) 6-5 Luke Humphries (3-3)
James Wade (2-4) 2-4 Gerwyn Price (4-2)
Gian van Veen (3-3) 2-0 Nathan Aspinall (3-3)
Danny Noppert (1-5) 2-0 Jonny Clayton (4-2)
Stephen Bunting (6-0) 3-1 Krzsyztof Ratajski (6-0)
Michael van Gerwen (4-2) 3-1 Josh Rock (4-2)
Chris Dobey (2-4) 3-1 Joe Cullen (5-1)
Jermaine Wattimena (4-2) 2-4 Damon Heta (4-2)
Ross Smith (3-3) 3-1 Wessel Nijman (4-2)
Martin Schindler (2-4) 3-1 Luke Woodhouse (2-4)
Mike de Decker (1-5) 0-2 Willie O'Connor (5-1)
Ryan Searle (2-4) 2-0 Cameron Menzies (3-3)
Daryl Gurney (0-6) 2-0 Michael Smith (4-2)
Dirk van Duijvenbode (4-2) 2-0 Jeffrey de Graaf (j)
Dave Chisnall (3-3) 4-2 Andrew Gilding (3-3)
Rob Cross (2-4) 1-3 Mickey Mansell (j)
Peter Wright (1-5) 4-2 Raymond van Barneveld (2-4)
Ricardo Pietreczko (1-5) 4-2 Martin Lukeman (2-4)
Ritchie Edhouse (3-3) 0-2 Dimitri van den Bergh (3-3)
Niko Springer (3-3) 2-0 Niels Zonneveld (3-3)
This gives final rankings of:
7-0 - Stephen Bunting
6-1 - Krzysztof Ratajski, Willie O'Connor
5-2 - Gian van Veen, Gerwyn Price, Michael van Gerwen, Damon Heta, Dirk van Duijvenbode, Joe Cullen
4-3 - Luke Littler, Jonny Clayton, Josh Rock, Jermaine Wattimena, Ross Smith, Wessel Nijman, Dave Chisnall, Michael Smith, Dimitri van den Bergh, Niko Springer
3-4 - Luke Humphries, Nathan Aspinall, Chris Dobey, Martin Schindler, Ryan Searle, Cameron Menzies, Andrew Gilding, Ritchie Edhouse, Niels Zonneveld
2-5 - James Wade, Danny Noppert, Luke Woodhouse, Rob Cross, Peter Wright, Ricardo Pietreczko, Raymond van Barneveld, Martin Lukeman
1-6 - Mike de Decker, Daryl Gurney
0-0-7 - Gary Anderson, Ryan Joyce
Hence 19 players would split the winning record prize, Bunting would of course claim the champion's pot. The only thing left to do now is to work out the post-tournament rankings. Here' the typical yardstick is to move someone up or down one rank (for these purposes, rank indicates one row on the initial ranking, i.e. each rank has two players, east and west, with the former being technically higher) for each win you have more than losses, or vice versa. However, promotion up to the top ozeki rank has special requirements in sumo (and similarly to the rank of yokozuna above that again), and similarly for relegation from that rank. We're going to assume that Humphries is not already in what they'd call kadoban and will not drop, similarly we're going to assume that nobody is in the spot where they could potentially promote to the top rank based on this tournament's results. Now it can become a bit complicated as you can very easily end up with more than one player at a new rank - indeed in this example, you have four players (van Veen, Bunting, Price and MvG) all with enough wins to get to the top rank you can freely promote to. Hence there is frequently a lot of manual fiddling, often resulting in some players moving up down more or less than expected, although it's usually the case that they will always have you moving somewhat in the right direction. As such, the next ranking might look something like this:

The last three spots indicate players who would have earned promotion from the division below. As we didn't simulate it, I'm just slotting them into the bottom three positions, replacing Lukeman, Zonneveld and van Barneveld, whose records were such that they would normally expect to be relegated. In reality, those promoted might actually have a bit of a higher rank, or those towards the top of the lower divisions might all have losing or otherwise not convincing enough of a record to earn promotion, which might result in a reprieve for one of those three players listed. Anyway, the worlds kick off in a few hours, so back to actual tournaments.
