If it's a hilly TT, your target power on the climbs will be higher than it is on the descents or flat. At least if you want to win. It's simple physics/maths. Any pacing algorithm (eg. Best Bike Splits) will always set higher power targets on the climbs (obviously taking account of your personal limits).
So, you have to game the physics and physiology to maximize how many KJ's you can put out for the effort........while minimizing the time spend going slowest.
So, assuming it isn't a mountain climb and descent TT......but just hills you can still pedal down. A good bet would be 105% up and 95% down and as damn close to 100% as you can bear it on the flats.
FYI.........I have more than one regional gold (in category) for USAC TT. And it's not due to monstrous power either, mostly efficiency.

The reason one would pedal like that is to avoid coasting, ty reduce the accordian. Just being a good wheel. Ive been riding a 42x18 ss so this happens when trying to follow fast guys on flat ground

This internal work is a sharply increasing function of cadence and the power requirement runs about 1.0 Watts/kg at 110 rpm. Formenti at Kings College has published several papers on measuring this within the last decade.
Yep, spinning at 150 RPM without putting out any useful power is incredibly pointless.

I didn’t know that was a thing for pilots. I do know that some railroads that operate in remote areas have somewhat similar accommodations. When I spent 2 nights in Edgemont, SD, I saw crews being shuttled to what looked like a dorm building.

Oh, that sounds better. This is a room with some recliners thrown in.

You will, but not as much as many people often post about it. Hence why I said about 10% over, max. The reason is physiologically, you cannot "bank" that much extra of your critical power for an effort of a duration of an hour or so. If you can do 300 for an hour your best standalone 20min might be as high as 318 or so. But if you do 318 once for 20min up a hill, go down the hill at a LOT lower.......you won't be able to still average 300w. That's not how ftp and critical power works.
So, you have to game the physics and physiology to maximize how many KJ's you can put out for the effort........while minimizing the time spend going slowest.
So, assuming it isn't a mountain climb and descent TT......but just hills you can still pedal down. A good bet would be 105% up and 95% down and as damn close to 100% as you can bear it on the flats.
FYI.........I have more than one regional gold (in category) for USAC TT. And it's not due to monstrous power either, mostly efficiency.

The Rolling Stones said "What a drag it is getting old." So, does drag increase exponentially with age, or is it more of a linear function?

Pedants R Us!
(Though a true pedant would point out that 'R' is not a word, and you really should use the subjective case, not the objective, and the word order is wrong.)
