Haven’t biked in years, starting over. Why’s everyone riding on less psi now?

So after a few months of drinking the kool aid and riding at 80.85, i pumped my tires back up to 95/100 for the past couple of rides - and it has felt faster (given the wind and wattage). Was it a controlled test? No. But that loop is my main training route and I have a pretty good idea of what kind of speeds I do at different wattages and under various wind conditions, and this does feel faster. Admittedly, this is on very good quality tarmac, though.
At least that's what the experts say. I suspect it's true though.

That's good, because if I had to prove I was faster, I'd have to show you just how slow my faster is.

It was sloppy phrasing on my part. By "feel", I didnt mean I had the sensations of going faster - I agree that that can be misleading (and I have noticed that several times - my bike feels sluggish but when i look down, speed is pretty much where it should be). I meant to say that I estimated myself to be faster, given the wattage and how strong the headwinds seemed to be on that given day.

All these folks mentioning their weight to the nearest kilogram or five pounds, and no mention of bike weight.
Your whip could be 6kg or 9kg...

We need our GPS units to provide simulated tactile feedback. Pick your target speed, and it gives you the feel-good vibration frequency when you're there.

This is why races have become so unpopular: people don't enjoy being shown how much faster others are in an objective way.

On top of the sanctioning body limiting change via rules, the practitioners of the sport use "conventional wisdom" and "tradition" to fend off change. Those words can be viewed as code for "we have no data, but we believe". They do crumble, but they die hard.
The notion that, if the pros do it, it must be best, is flat wrong.

Bike racing, like most forms of racing, has rules in place to actively control the impact of technology on the sport. But bike racing takes it further, managing any change, whether technology or simply design. Change does happen, but it's slow.

You doing a solo ride has significant differences to a mass start race: you are pushing air all the time at a much more constant effort, so an efficiency gain which will affect the whole ride, if there's one to be had, is more worth pursuing than optimizing for the decisive race winning (or losing) parts of the race.
When you get into it, there are reasons road races are ridden with setups as they are, TTs and tris with setups as they are, and so on, which is all informative if you take into account the context of the respective races. Typically, what the pros are doing is right, for the situation they are in. Rarely does someone successfully do something unique and better, and then they do it becomes the new orthodoxy (or banned by the UCI, haha).
