Regarding the seat tube - Yes, the effective STA shift is correct in practice too - I am also not a fan of steep STAs (an odd development in progressive hardtail design that I think has gone way too far) and it is striking how much the seat tube kink corrects for what the Geo chart shows relative to other hard tails (most recent example is from a small local company out of Whistler, something about Chrome, or Mags, can’t quite remember).
The net “knee feel” when seated is more relaxed, I don’t feel pushed onto (and fighting against) the handlebars, and the saddle doesn’t get jammed in my jammer - over all result is that seated pedalling on flat or uphill terrain is comfortable and more efficient.
