In a new barrel with something they can see inside it with, like a bore scope, they will see straight scratch marks the lapping compound made. My memory sez they use 150 grit to lap barrels before they sell them. Those scratches don't last forever, however. The best Group Shooter ever to live said the first 600 shots through a barrel are the best ones. Perhaps it has something to do with those straight scratches??? Perhaps one could periodically cast a lap , apply the 150 and put the "New" back in they barrel

Doesn’t sound like it really matters then, does it.

I guess it depends
on what one believes and has experienced. Some barrels' seem to perform very well regardless. In reading what the Long Range shooters do, a lot of them don't clean very much, can't actually. Now, how do long range groups compare to 1-2 and 300 yard groups? I don't know and have never seen the subject discussed.
I see friends using a number of different bore cleaners. Some of them use Butch's and I've seen more of them using Patch out of late. I've been using it for two or three years.

get your barrels one of these. https://www.amazon.com/gp/product/B07TTQF24F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Keep in mind it is 20X.
They even have one for pistols. https://www.amazon.com/Borescope-Cl...2-Inch-Diameter/dp/B08D67H7LZ?ref_=ast_sto_dp
Plug into computer with Win 10. Win 10 has a camera program.
I used to use a flashlight in my pistol barrels. Was bored one winter. Used the Hawkeye on a pistol. WOW! I was not getting them clean.
So I now use the Teslong borescopes after cleaning on everything...
they do not compare.
more time of flight
more time in the wind....wind maybe 30 plus feet above line of sight
having said that
bart has a 5 shot 600 yard record of about .3
and i think there is a 1. at 1k that is probably 5 but maybe a 10.

That's tiny
No question, Is the .3 after reducing it for the distance? Doesn't matter too much cause .3 is tiny @ that range anyway.

no, actual measurment
YES BUT
the scoring committee sent it back as .311...still a record
the 282 is the range measurement.
ohh and a NO TURN NECK
