Preseason doesn't really count though, coaches use those games to try things out that they wouldn't do in a game situation e.g. the number of times they go for it on fourth down. The kickers are still making something like 93% of PATs so it's still going to be the go-to option.
Doesnt it mathematically make more sense to go for 2 now?
ie 100 PAT @ 93% = 93 points
100 2 point conversions@ 47.9% (the historical average) = 95.8 points
I guess the question becomes is the current 2 point conversion rate greater or less than the historical average
