I would say the pressure problem for noobs would be across the board with all hones not just 1 k.
It's a matter of horses for courses with stone choice. A 3k stone can't do what is required of a 320 grit stone & vice versa, however, with a setup like Livi's, a 320 grit would be redundant as it seem 1k is also for him.
The 3k Livi used to reset the bevel on that razor was ample for that job. The blade was new & needed minimal grinding for restoration.
Even if a blade need not be taken down to 1K for a bevel set what harm should it do besides removing more steel than is really necessary? I still don't see why and edge should crumble but whatever.
