I have done fairly decent sized descents and not had an issue
That's not really a sample rate. Subjective experience aside, as many on here have done the same.
My experience stems from a fleet of bikes, set up evenly, maintained regularly, ridden over varying terrain in diverse conditions.
Statistically, there was a higher failure rate from 140mm rotor equipped bikes in relation to 160mm equipped ones.
Whether this proves causation, I'm not a statistician so I can't tell you. Maybe the 140mm equipped bikes had brake dragging noobs on them and that fucked them up and vice versa.
