If Robochallange run with the "in the pit your out" then it could be argued they are not running an FRA event! (They ARE sticking with the rules so it defiantly is an FRA event) the rules are fixed and took ages to get them sorted last year, I'm not entirely happy with them, but a compromise was agreed by a democratic vote of the roboteers. and all sides will respect them.
The Euro champs were run by Ed Hoppit. I don't think it was an FRA sanctioned event so he could make up the rules as he wished and so he did.
I do get a bit tired of the "in the TV series the producer introduced this rule" they are not in the loop any more. They are making "reality TV for the brain dead! the rules were made for good TV that's all. They didn't care about the sport they just cared for themselves and the money they could make out of the hard working dedicated roboteers that deserved a much better deal than they got.
