As a serious question, which came first: the bunching or the FF cutdowns? Because I wouldn't be particularly incentivized to attempt a FF unless I know I'm behind, given that I won't really get to save any real time from it the next day.
My recollection is that the Fast Forwards were cutdown before airport bunching was used as a means to keep the race close/costs down.
An unfortunate side affect is that it makes going for the first of two Fast Forward passes a poor choice because the last time a team went for it all of the teams bunched at the next airport and the team that checked in first is the only team that definitely cannot try for the second Fast Forward. Some reward.
Since the Race is all about avoidance of risk (stay with the other teams, book the same flight, do the same tasks, don't break away from the pack) it makes the Fast Forward an unattractive option for all but the teams that lag the farthest behind who have nothing else on which to hang their hat.
