Should be done everyday. From Friday to sunday ^^
And implying being carefull when picking lists up just means some playstyles aren't ETC top tables (where plays are slower because tactical moves are more often done with extra care) compatible. I don't think that is the intending/ expected conclusion one can look for. Nor that the game should end up before 6 turns are done.
I'll be coming with à chess clock nest year and report slow play (havent expériences stalling). I just think this is going to stress up the game unnacesserily. Whearas 30 extra minutes would have done the job without hurting anyone.
To your other objections:
- If finished early you can go and watch games, have a beer, socialize at the venue (easier than the evening where teams go to eat/ do next game pairing together)
- For driving/ flights. I think most arrive on thursday (îf ont earlier) and leave on Monday (if not later).
Anyhow, I think its a shame games dont always end as it has been designed as a balanced 6 turns game.
