Well, er, but, you see?
I've had mine off several times, and though I've never actually used a magnet to find out if it is solid steel (hint, hint), I do know that mine's never been retorqued to anything close to 95 lb/ft....really!
It is hard enough even with someone holding the rear brake with the bike in gear to put that much torque on it....an impact wrench would be better, but I use a mallet on the breaker bar handle. SO, how come this happens? Is it possible that the previous person didn't install the locking tab washer on the shaft correctly. If I recall, the washer matches the splines on the shaft. What if the washer was installed wrong. Isn't the inside of the nut recessed to go over the splines?
