I am for the lottery system where, Dale takes your best time from a practice session he chooses. and it's random.

this way it will keep some people from throwing on new tires, since they won't know when to put them on.

and lets say you go slow all day long and have mechanical problems and just generally suck that weekend, then you get a "provisional" where you can use your best time from the last race weekend. as long as its the from the same track.
