Clearly, you have no clue.
Apparently, you don't understand frame reach. STA is not involved. It's also irrelevant if the saddle is always placed in the same position, relative to the BB. I'm well versed in trig.
Before frame reach, TT length was used, but the STA did affect comparisons. It does not affect frame reach comparisons.
I also keep in mind the bar height difference between a -17 stem angle and a -6, which is about 20mm. With integrated bars, the -6,7 or 8 angle is usually the only option, so I can use a smaller stack. My latest frames are only 505mm and there's 10mm of headset top cover, plus 10mm of identically shaped spacer.
