So I can't say if they improved due to tire pressure or not

31/32 cold goes up to about 40 hot on hot days, 38-39 on cooler days

35 cold went way past 40...X.x.
Then it sounds like your starting pressures are OK once you adjusted them down. However, if you consistently run better lap times on a hot day then you should adjust your cold pressures up a couple of psi on cold days so hot pressures are always at 40 psi.

BTW, sorry to read about the nut job
