The SOLUTION is to assign Refs to a series and don’t rotate them around game by game. Teams would understand what they can and can’t get away with. Instead of a game by game variance in tolerance. Warnings to players would carry over.
In short it would be an improvement over what we have now.
The problem is that even game to game the same ref's will call things differently to "manage the game".
What I really wish would happen is that the ref's would have to answer questions (either publicly or from the league) about why some calls happened. Maybe do video things on it after each game, but wait to release those video's until later. Or whatever. But there's been plenty of times that you see something and wonder how the f*** did you manage to f*** that call up that badly?
Unfortunately the NHL doesn't want this as they do not want fans focusing on the officials, but the on ice product.
