I think I'll stop discussing this further after this post, my own personal experiences go in a different direction. Sorry, if I state the obvious again below.
When I play free improvised music, same result. I got the feedback from the audience that it was obvious. Having me ears not trained in those areas as much as you have, my results tend to be a lot more basic than what you do.
When is the objectively perceived point to move on to make music?
Your position is backed on where you are musically and I respect that.
With unknown music - playing a Standard I never played before, sight reading in the orchestra - for me, it always helps my intonation and makes it more musical if I pre-hear or vocalize what's about to happen.Any jazz player should have the same experience for anything not pre-given as well as any pro reading down music they don't love.

When? When you can play a 3 octave C-Maj Scale with all possible fingerings on all strings at maximum tempo perfectly to the recorded piano?Those are musical decision to be made at a later date.

I'd like to point out, that you tell on me about things that from your point of view can be decided later. And here you rise a point to help state your view where I can clearly say: this is so advanced, nobody who thinks about incorporating the 3rd finger into his playing will need this info.One of the things about improvised music intonation is the the tuning of the more common extended techniques, for example, a saxophone multi-phonic become part of the collective music, in addition to the pitches needed to harmonize with it.
To bring it back on topic: to be precise about an interval, you have to clearly be able to hear it first. Which finger you use to hit it is secondary as long as you make it precise and repeatable and works for you in the musical context you're in.To bring it back on topic, practicing the western tuning is just about being precise
