Pulling a goalie is usually because the goalie wants to get pulled and not really due to a strategic decision
They are in general a moody and superstitious bunch, was watching the game today and figured holtby won't want to get pulled with the rookie breathing down his neck and earn me some more save equity... He then started in and kept letting in more goals... Thing is I pivoted from Blackwood to Holtby last minute to Dave $5 to upgrade elsewhere, that was a -40 point swing and missed the call line by 1-3 points in most contests
Patrick Roy was of the "if I'm not feeling it take me out" his coach left him in longer than he appreciated and told the gm he was done playing for the Habs before the game finished

Haven't checked the math, but I would imagine you could heavily weigh chance of getting pulled by coach and goalie personality metrics - I'd be shocked if some coaches/goalies don't pull significantly more frequently than others
