I think there is a problem with language here or something.
No one is claiming that with experience most people dont learn to estimate distance/hold without thinking in terms of meters/yards etc and without doing calculations - at least for close distances. Its the same as gapstinctive/split vision/shotgunning.
Its not a big deal essentially everyone learns it do a degree with time spent shooting. Some better than others.
But thats not what "instinctive" has referred to for the 10/20/30 years. Generally the "instinctive" thing has been defined as not using the arrow(or a sight) for aiming. The whole "not seeing the arrow" thing. . Its a fair more controversial idea than trusting your gut and and experience on how high to hold the arrow. Not seeing the arrow is not actually possible and trying to not see it doesnt work for many people.
If when you say "instinctive" shooting you just mean estimating distance without numbers or calculation you are changing the definition and you getting yourself in an argument because it seems like your saying something else.
You may be right, lossy translation or something.
Still, when I at least are shooting well instinctively there isn't any conscious estimation, yardage or otherwise. There is no "it's that far away so I need to put my point there", you do just look at the spot and the rest takes care of itself. My arrow point is never in focus and when I am shooting well I truly don't actively see it, no. It could just as well be a stick on the ground along the shooting lane. It's there but I'm only looking at the spot. I know my point is there however and it's BS to say I'm not using the point as a reference - of course I am. Just not consciously.
The driving metaphor is a good one - we don't look at the bonnet, just the road ahead.
It's not witchcraft, voodoo, or anything particularly special, any more than catching a ball. It's actually kind of simple, animal, and is only reasonably consistent after a load of practice coming to grips with your gear, the potential energy in bow, your confidence and of course focus. To be any good takes a lot more practice to attain the same accuracy as conscious gapping known distances, for all but the innately gifted, in my opinion. Which for some of us makes it all the more rewarding.
I think this is what the OP was referring to, not intending snark.
