You are one argumentative dude pep, I'll give you that.
That said, I still don't see teams thinking about this the way you are. First off no team scores 100 tds in a season or even comes close to that. Most years the top half of the league scores probably between 40-60 tds.
Just looking at last year, the top 10 teams in PATS attempted (which should be pretty close to number of tds scored, I couldn't find total tds by team or 2 pt PATS attempted by team on ESPN) missed 6 FG's from 30-39 yds and missed 3 PATS. Our kicker Bailey has made 38/40 FG's from 30-39 yds in his career, which is 95%. If you assume 50 tds in a season that means he is likely to make 47 or 48 of those. You'd need to be successful on 24 of the same 50 to make the total pts a wash. I don't know what the historical number is for the 2pt conversion (I believe you posted 50%) but even if you can make a slight improvement on that (as you suggest some teams might be able to do by going for it more) is it worth the risk? There's a ton of close games in this league and 1 win or loss can make or break a season (just look at our team the past 4 yrs, 1 more win each season would have netted us vastly different results). I doubt most good coaches would view taking the risk on of potentially giving up a pt or two on a week to week basis as a good thing. And even if you can get the total points to a wash or slightly advantaged, that doesn't account for the one game where not getting it cost you a win or going to OT. You cant get that game back, even though statistically you might make up for the point shortfall in the long run.
I still think the only teams that would give it any serious thought are the one's with mediocre kickers or perhaps in situations where weather is a significant factor (wind, extreme snow/rain).
