http://www.redhotpawn.com/tournament/listall.php?view=finished says it all
for a tournament to finish fast it must either:
have a huge group size, (which sucks because this makes players take massive numbers of games at a time, which is prohibitive to most players)
be 0 or 1 day timeout,
have ANY timebank!!!!!!!! ( we can have holidays and freedom!!!!!!!)
and be 2 rounds or less (acheived by having intermediate group size).
