Yeah, no doubt. But if you care about speed so much as to run 5-10psi more you'd better be riding in a San Remo Speedsuit every day as well.
And in real-world results, this may not be the case. Drum tests tend to prefer higher pressures but on non-perfect roads with a human being onboard lower pressures may be faster. And it can be different from rider to rider.

Ok so lower pressure in the real world, new tires for most aero, wear a speedsuit all the time and HTFU.

I'm going with fitness. My level of comfort varies depending on how hard I go and how fit I am at the time. When I'm in peak shape, 100 miles of hard riding and I'm mostly fine. When I'm off form, I'll begin shifting around maybe as early as 30 miles into the ride if we're going balls to the wall (which is often exacerbated by riding in a very aggressive position).

Surely, it's proportional. Longer races necessitate comfort, shorter races not so much. If you can stick it out for a few hours, it's comfortable enough. Better shorts and tuning your fit would be my recommendation, not changing bike. Hammer on. It only lasts as long as it lasts.
I say that having done a few 300k days on a CAAD10. I don't reckon there'd be a meaningful improvement using my Synapse or SuperSix, in terms of finishing time. If you aren't prepared to embrace a bit of discomfort, why race? The pain of properly trying should dwarf any bike concerns.

I think a lot of people have their bars too low and their tire pressures too high, then their backs hurt after 50-60 miles and they act like they have no idea why. Also I'd wager most cyclists aren't stretching enough or properly.

Yes, because many of us mimic Pro's. We get rid of spacers, slam that stem and mount deep wheels. Every time I ask "why"?!

Aesthetics and vanity. It's why I slam my stem and have deep wheels

I'm actually more comfortable with the current position which is a -17 stem slammed on the dustcap. The fitter had me on a 100mm -7.

Correct me if I'm wrong but riding with flat back is modern evolution in pro peloton.

Do you ever ride in the drops?
I'd say: set up the bike so you can use the hoods and the drops. Then, use the drops for shorter rides. And the hoods for longer ones.

I do use the drops on occasion (sprint on flat or uphill and descending). My FTP is low compared to others in my category and while I'm working on improving that, the quick fix for me has been aerodynamics and efficiency.
