When in doubt... build hell-for-stout!
You sure like black and white rules for rather nuanced engineering approaches.
If less than 10:1, always do Base Drag Hack, else don't do it.
If LPR or MPR less than 4 ft, then do swing test.
What is the significance of 4 feet?
At some point it becomes a function of rocket length vs usable string length. A 4ft rocket length maximum works for me and most folks that are swing testing rockets.
What about HPR less than 4 feet?
Sure, go ahead. Wear your helmet.
