In short, by attending at least three of the six events you are entered in to Championship. Your top three results will be scored and the top coach will win a trophy to be presented in September at the Exiles Open.
To qualify for the SWTC you must attend at least 3 of the 6 mentioned tournaments. Your three highest placings in the ones you attend will used for your score, however there must be at least two different races in those three. If you take Wood Elves (for example) for a third time your lowest score with them will drop off and not be considered, or if you take Skaven to all six only two will be considered for the SWTC score.
The coach who places first will receive 10 points, second 9 points, third 8 points and so on down to 10th place winning 1 point. Everyone else scores 0. Then every coach is awarded a bonus point for every full 10 players below them in the ranking. Finally every 0 is changed to 1.
This means everyone scores for playing and those that top the tables at larger events (inherently harder to do) earns a few more points to reflect the extra challenge.
Alongside this is the SWTC Stunty Cup. The highest placed Stunty Coach will receive 10 points, second place 9 points third 8 points and so on down to 10th place winning 1 point. Everyone else scores 0. Then every coach is awarded a bonus point for every full 10 players below them in the ranking. Finally every 0 is changed to 1. The "two races" caveat on the main score is dropped in the case of Stunties. Qualifying Stunty teams are Goblins, Halflings, Ogres, Lizards with no Saurus and Underworld with no Skaven.
After the points are counted at Exiles Open in September a trophy will be awarded to the highest placed Coach and Stunty Coach.
I hope all that makes sense to everyone, if it doesn't please ask here and one of the organisers will, hopefully, pop in and answer any queries.
If this is successful it will continue to run each year.
