AS i've mentioned before with the advent of 'assumed' thrust takeoff techniques one 'bugged 'up the V speeds to the assumed T/Off performance-to equalize the actual to assumed...
In fact one would reach V1 earlier with the actual(cold)temp than the 'assumed'.ergo the accel/stop wouldn't be equal..the padded V2 would also perform in the air as per the reduced thrust (hot)V2
Cheers..
