Caveat: In that mosfet's datasheet, figure 6 "static drain-source on resistance" has the wrong graph. It's actually the graph for diode forward behavior, same as figure 11.

Yes, good catch. I used figure 10 to get the Rds(on) multiplier value for 100C. Even so, a 1.2 multiplier at 100C seems a little low, IIRC.
Still, the stp80pf55 is an amazing P-channel part.
