There's a guy my age who works at an indi shop down the road. No one would accuse him of setting a breakneck pace, but then he tends not to break much of anything. He knows how much force to apply before changing approaches.
Then I had a friend who was a retired Air Force tech. He rebuilt a couple of old Jag twin cam sixes and an Austin Healey six. He too worked at his own pace and worked smart. Personally, I don't want to think about him with those huge sixes on the end of a chain.

It can be done, but you need the right approach and the right environment.
