Thanks for the links @MarsLander !
Especially NACA 2941.
This plot from NACA 2941, page 11 looks very familiar ...
... compared to accelerometer data from a 1998 flight on a K700 in a 2.95 inch x 71 inch LOC Vulcanite upscale ( n = 24 ):
Versus OpenRocket, where the quality of the finish has a major effect:
... I need to learn to fly HED so I can reduce my fineness ratio from 24 down to something a little lower so my rockets will go a lot higher and faster ...

I actually made four flights on this rocket. These are the Rho-Normalized drag-vs-velocity plots:
