Ok, I know I'm crazy.
I have a theory on pindle runs, and tried it on a decent sample (500) while drunk. When I'm over 470 mf, nothing drops, almost no S/U. When I'm around 460, I start to find S/Us. Since pindah is just bugged (no extra drops at /p8), could be a relation between mf breakdows on pindle? Something like 100-250 = good; 250-300 = bad; 400-469 = good; 470-500 = bad.
I remember having the same feeling a couple years ago - taking out 10 mf and getting better results...
