I'm wondering, with this discussion popping up and the battery discussion, if the event supervisors will step up enforcement of this rule. Awareness seems to be quite high, and with the GDC's ruling on the battery issue, they should really make sure the rule is followed. At Wisconsin they never checked/weighed our parts, they trusted us to do the right thing. But that might have just been because if they had taken the time to check everything, half the teams would be frozen solid
Just take extra care to make sure you don't goof up.
