Yeah, I know that taking most manufacturers ESTA seriously is normally a joke, but it seems here that trek measured each one at a relative height for the size (would have been good if they noted it), because with a bent ST, the angle would slacken as the seatpost is extended, which would happen as sizes increase.
My bars are normally about 1" lower than my saddle because I have long arms, if not I feel like the bike is squatting down with me. I've tried even 74.5* real STA and by the end of an almost consistent slight (about 1,000ft) climb over 10 miles, my knees were feeling it, luckily Banshee have the adjustable drop outs and mine were set in the high position, so just lost a degree going to the lowest setting and was fine for the rest of the ride.
For me, with my size 13/48 shoes, I like a plumb line dropped from the back of my saddle to intersect the chainstays about 14-14.25" back from the BB and my BB to top of saddle measurement is 32.25"/820mm, with either 175mm or 180mm cranks, hence the variation is length depending on bike and crank length.
