WAY too much time was wasted lining up, even for some members of winning alliances. This might change in later weeks, but the teams that carried victory were the once that took no time to line up, and simply drove into the pyramid to line up for shooting, or into the alliance wall for loading.
Few teams can floor load well. 'HOT arms' dominated this weekend. Also,
floor loading isn't necessary for victory (but it can speed up cycle times considerably.)
There is no excuse for not 10 point hanging. Not hanging lost many teams many matches this weekend.
Crazy high penalty points can all be avoided by smarter maneuverability.
Avoid the enemy pyramid at all cost, either by ducking under it, or hugging the side of the wall. EDIT: And not defending a robot when they clearly can't or shouldn't be defended (loading zone!)
Most Linear shooters are capable of full court scoring. Be prepared to defend it even if you haven't seen it from a robot earlier in the tournament. While short robots are nice for avoiding penalties,
there should never be an alliance of three short robots. Edit: If there is, tape something tall to one of them
Most importantly: Never leave a robot off your pick list because they are 'too good'. Sometimes even the best of robots can slip past the scouts of earlier seeds, and even be available as third robots. Edit: I'm talking about you; 910!
EDIT: A top heavy robot is a fallen over robot. I won't feel bad for you when your robot falls over if you designed it to fall over, no offense intended.
Also the impact of 'Robot in 3 Days' is very clear even at week one. A huge thanks to the guys who thought of it/put in the effort to actually do it! You're changing the face of FIRST, and making every match that much more exciting.
