I could be out to lunch but in my mind another line of thinking is:
If P-1 is so fast now relative to PRP let it find as many factors as possible and save as many expensive PRP tests as possible. Maybe it should be 2.5 or 3 to 1 tests-saved?

Similarly it is because GPUs are SOOOO much faster at TF that we bumped the pre-PRP TF by a few bits to save PRP tests.
