Not really. This is absolutely the most common reason for stripped gears. The spur gear is almost always the culprit, as Sosidge said, it's the weakest link.
Just imagine this. Hold your car up, accelerate to full throttle, then cause your front wheels to come to an sudden stop while under power. Try this a few times and you'll strip a gear. This is exactly the loads your drive train is under when you "bang" the boards.
The reason the Mini veterans don't go thru gears very often is that for one they don't bang the boards that often. The other is that when they make a mistake big enough to take them into a "board", they do it off power.
