I think you are reading too much flexability into my format. I had suggested a minimum of 9 Throws per e-mail, but that they would terminate as soon as a winner of a set was decided and not necessarily carry over into the next set. (9 throws should be statistically enough to resolve most (but not all) sets).
Given your example both players would have to submit a minimum three gambits per e-mail - however they could submit more (ie: If you knew you were going on vacation for a week, you could submit all your throws at one and "let them ride").
I thought about a seasonal format, but was dissuaded by the length it would require. My thinking was that it was better to try a shorter format and then, provided no major holes were discovered, adjust it for future tournaments.
As it stands, I think we'll find the tournament to take quite a while.
Barring any serious objection over the next 24 hours, I will consider my proposed format cannon for this inagural event.
The question of when you would like to begin is a good one, with the holidays approaching. Thoughts?
