We did try the three race per weekend several years ago, but it wasn't liked very well. The theory of tire management sounds good, but realistically didn't change much...except make the last half of the race a HPDE session when the cars got all spread out.

I love the Hallett format and the one 40 minute race. I wouldn't be opposed to another 40 minute race ... But not at tracks like TWS where we already get separated in a 25 minute race.
