Now because I used the term "blast" you try to turn this back on me as sounding like I'm the problem in this conversation?

What? At most I am implying that you took it too personally and even that isn't saying you are the problem.

Those points can not be argued.
Tell you a little story. Decades ago, I rode light 23s at 140, both ends. Side wall pressure was 160. I could out-coast everyone. I had a very fast riding buddy, shorter than I, same weight, who slaughtered me climbing except I'd get him back on a long descent. He asked exactly how I did that. I told him about the tires and pressure. He put on those tires at those pressures and next ride, dropped me on a descent. It all depends on the road surface texture. I don't run 140 anymore. The tires we get now are not as supple and little bumps bother me more than they used to, so I run 80 front and 100 rear and still drop everyone I ride with on descents. My guess is that stiffer tires don't need/shouldn't have as much pressure.Everyone seems to think that their riding conditions are universal. They're not. I cornered as fast as anyone and had lower times than I should have on 400k brevets, comfortable the whole way. Ah, back in the day.
You might want to look at smooth roller data. For sure lower pressures are faster on cobbles and rumble strips. We know that. In between, there's a gray area. We have to experiment with our tires on our pavement.

Obviously softer is "faster", according to the same bike industry trying to push us all to TL hookless at 72 psi max .. Hook line and sinker! haha! :-)
EDIT: According to an other currently active thread, weight also doesn't matter .. Sure it doesnt!
Next up a 10w dynamo to power the gadgetry, - electronic gear, super computer, radar system, safety lights and ABS brakes ...

65PSI is the sweet spot for me. I tried 70, I tried 60. I don't believe there would be any benefits from increasing my pressure.

No its not, as seen in the link/data provided before. Except if if not realy road riding anymore. Ppl claim the data support their claim, but no. Take a look for yourself.
