Also, I'd like to make one comment about the pace lap speeds. There's really no need to enforce the different speeds for PT & GT classes for the whole pace lap. I'm glad Sagaris didn't follow it to the letter, because on a 6km circuit the speed difference means that at 50mph the PT field needs 4:30 to go around 1 lap, and the GT field needs a whopping 5:32.
Apart from the fact that this is already excruciatingly long, this means that the PT-field is already more than half around the track when the GT's start their race (Actually, in the case of Monza, the PT's would have been at Ascari in the first lap when the GT's start their race). This also means that after 2 laps the PT's start lapping the GT's, when both fields are still going tightly together.
I think that, if the goal is to leave a little bit of a gap to let the PT's get safely through the first corner, it's enough to enforce the different speeds at the grid formation point. You still get at least about 10 seconds difference, which is by far enough for safety, and it gives a little bit more time for the fields to sort themselves out before the lapping begins.
Just my opinion.
