I feel like goalies rely a lot on the average TPE of the teams around them and that they face. For example, goalies in the J have more noticeable performance gaps between 155, 350, and 425 because the applied TPE range is smaller.

The SHL is more random for goalies because the range is wider (155-2200+), but in looking at the numbers, the average of the best goalies since S53 (determined by award noms for simplicity) is just shy of 1500 TPE while most winners are between 1350 and 1650 TPE. I think if we wanted true goalie parity, it would be worth investigating the effect of moving to a max applied cap and minimum TPE for skaters.

If that seems extreme, cutting goalie cap hits in half or nulling them below 1200 TPE (rough league average) would be the methods to look at. At least, in my opinion.
