I see that that I'm missing an example/reference for: PP1c, PP3a and PP3b.Quote from jack hershey:
T2F's.
On your list, you see PP6a; it is three consecutive T2F's.
Thanks for asking.
Is this "deduction" correct:
PP1c = Three accelerating T2F
PP3a = A T1 between two consecutive P2
PP3b = A T1 between two consecutive T2P
