I'm looking at some other teardrops and one has a little more aggressive early curvature like your NACA 0039
section and I think what you have would make a fine tool to work with,especially since you can get such specific vectors at any position.

I'll never 'finish' looking at this stuff,but I think we're closing in on a useable 'Rosetta Stone' for decyphering the air.

Outside everything else you wrote which is full of aha! moments and I always get more insight,
That last part, 2.5:1 template over the top and 4:1 down the sides, pretty much throws us back into the range of the bluefin tuna and other aquatic kin.
Thee 0039 equation & spreadsheet has been great to be able to throw numbers in and study the outcomes and angles and that's why I was looking for an equation to work with, just think it's much easier to take a set of numbers out, mark them on the sectional areas, then cut and join up than trying to set angles as you go.
I do need to go back and revise the spreadsheet to allow the use of different curvature for the x & y coordinates, with the new knowledge that I have absorbed.
I think you are half right with the rosetta stone, but no doubt, once you have whaqt you think is the "perfect form", another stone will be turned over to reveal even more details of perfection.
