UPS - Universal Points System & Subjective PtSys.
BTW, imho, current 2012 F-1 pts-system is one of the worst in racing and same is about F-1 1991-system (10-6-4-3-2-1).
The best of F-1 systems is 2003 Top-8 (10-8-6-5-4-3-2-1).
But one of CART systems is better: Top-12 (20-16-14-12-10-8-6-5-4-3-2-1).
And one of MotoGP systems is much better than current F1, but starts from same 25:
Top-15 (25-20-16-13-11-10-9-8-7-6-5-4-3-2-1)
As we can easy calc: 25-5, 20-4, 16-3, 13-2, 11-1, etc.
