Personally I think the 'player rage timer' is measured in wipes. Each wipe tends to bring out the worst in people, with the shorter fuses only needed a single wipe before exploding. A good run, even overgeared, doesn't set anyone off so it's hard to equate overgearing to an abstract idea as 'player rage timer'. Nor is it universally applicable. I, unlike many, will keep trying, wipe after wipe, until the party as a whole gives up because I don't believe in giving up. As such, I'm not a very good indicator of 'player rage timer'.
