Chance of success = MIN(SKILL - (.75*trivial) + 51.5, 95) -- this is for things w/ trivial higher than 68.

100 skill (100 - (.75*235) + 51.5 = 100 - 176.25 + 51.5= -24.75 = 5%
150 skill (150 - (.75*235) + 51.5 = 150 - 176.25 + 51.5= 25.25%
175 skill (175 - (.75*235) + 51.5 = 175 - 176.25 + 51.5= 50.25%
200 skill (200 - (.75*235) + 51.5 = 200 - 176.25 + 51.5= 75.25%

Those are your odds approximately at sub-trivial levels. Also 5% fail on any given combine too, trivial or not.
