You’re not wrong on the EP(PG)/gp being essentially arbitrary in saying that the Flames goalies are perfect. What I’m trying to use it to show is to compare Flames goalies year over year with the baseline of a perfect goalie to compare every year to. I’m not trying to say the Flames goalies have been objectively good or bad, just how they are relatively to their past selves.

Yeah, we spend a lot of time thinking about and discussing what leads to goal prevention and goal creation. The data just isn't publicly available in a format that lends itself to analysis.
With respect to goal prevention, there are three things that I can think of to optimize it:
(a.) Shot volume suppression
(b.) Shot quality minimization
(c.) Goaltending skill
Improving any of these will intuitively also improve goal prevention. A is easily quantifiable, but B and C are much more difficult to evaluate given what little data we have. Also, A in isolation is somewhat meaningless without knowing the context that would come with knowing B.
I think that's why the discussions typically devolve into eye test arguments. Which is sad, but we crave the ability to attribute outcomes to some knowable set of events.
