I had always tightened the cassette lockring until it clicked a few times and called it good. Never had one come loose on the road. Someone on the forum suggested that might not be enough so I dragged out the torque wrench to check. Eye opener! The recommended torque was much more than what I had been doing. I still don't use the wrench each time but I crank them down much tighter than before. Yes, they are more difficult to remove
Through the years I've been on rides with three folks who had cassettes loosen up. Temporary fixes aren't too difficult but each time it took awhile to figure what was going on.
