Hands aren't tiny, but with wrist line to middle finger tip being just under 7.5 inches and my middle finger coming in at 3 inches long, my hand is mostly palm.
I've tried to replicate things like this but I just can't keep my fingers consistently wrapped around the grip, especially the pinky and especially when trying to have the fingers perpendicular to the grip along the 'palmar digital crease' as written in that thread. That's with a standard grip with no extra wraps. I feel like the grip moves in my hand and I tend to get weird skinny callouses on the blue lines here. This may be more that my hand doesn't like cord, but still.
If you numbered the segments 1 to 3 with 1 being by the finger tip, I feel like my hand is more comfortable when the grip is aligned diagonally in lead hand, resting on the pinky on segment 3 (slash the crease below) and resting on the index on segment 2 (slash the crease below). I also know that just because it's comfortable doesn't mean it's functionally right.
When I do manage to execute a full swing without feeling the club moving in my hand it obviously feels insanely crisp and solid in comparison to other swings when it moves.
I just bought a full set of Undersize Tour Wrap Microsuede to test out a handful on clubs, before I regrip all 13, but I figured I'd run these thoughts past TST. I'm going to try to share a video taking my grip later today or tomorrow morning.
