I dunno why but the 0.003866% doesn't seem very accurate in my case, i've done 19836 pindle runs with 800 mf (give or take), and i've found 3 WF so far. And if 0.003866% is correct, i shouldn't find my first windforce until my 25866th run.
Through Experiment, with 800 mf, and about 100 mf on my merc, a windforce drops every 6612 runs, or 0.15%. 0.15% is considerably different from 0.003866%.
