Smooth bearing is important. But how much more smoother can be that much significant when everything is well tuned altogether.
There are many people who think that free spinning using fingers is enough to measure the car real performance on track when it's not.
I was particularly referring to those who thinks that their bearing is very smooth after dipping in zippo oil and doesn't want to relube them anymore because "see how long this bearing can spin wow!". But then there's the sound of grinding ball bearings inside lol.
For example, when you have wheel bearings, when on the track, the smoothness the wheel can spin is only up to how much the motor drag with all the gears attached together.
It's the same with cars. You can dyno on flywheel and get 200hp. But when you put it on an on-wheel dyno with all the wheels attached and car load, there is probably only like 160hp or so.
Get my point?
I get your point bro..

What i mean is, smooth bearing is one of the important thing plus with roller positioning..
What u said is true but u cant 100 % compare it with real cars..

Normal car load forced the weight down to earth..
Tamiya Mini 4wd car load is forced to the track wall during cornering.. I have try the bearing with no lube, re lube a little bit and original factory lubricant.. The result is vary... But if u said sound like grinding, the bearing memang KAPUT dee.. I also have experienced new bearing from packaging KAPUT too.. hahaha
Its my 2 cents bro..
Sharing my opinion only..
I like your statement too about ur way of thinking..
