WCG I am pretty sure they will bunker. They say they can not do a set time. They are not setup for that.
PG is always a set time with no bunkering.
Bunkering is part of the challenge, if we do not bunker they will have a 48-72 hour head start.
It is a PITA to bunker but it is not all that hard to do. I my self have no problem with bunkering. It is not cheating if it is part of the strategy.
Bunkering is not going to go away, they have been doing it for years. So we go into every challenge with a huge handy cap.
