With pump gauge, tip bending, sausage leading edge feeling not being exactly reliable, I wonder what the note frequency is for a ping test?
Eg middle A is 440Hz.
Could use a guitar tuner app to ping the wing reliably, would be music to my ears ;-)
Sure, if you have good tone recognition.
Done it with a dozen good winger's wings, and all look at me confused.
One is a pro musician.
Don't need tone recognition.
Just need a guitar tuner app to recognize the frequency for you

Does it also go out winging for you?
I take my phone with me when sailing alone in cold water (like anytime now) for safety in an Aquapac and Life jacket.
The ping is binary. There is no progressivity of pingness. It either pings or goes thud. If you keep pumping after it reaches ping then you will eventually damage your wing.
Large diameter struts need relatively low pressures. Even pingworthy pressure is higher pressure than is necessary.

I wondered if wing shape, skin material, stitching, all need the same skin tension regardless of size.
Just by physics alone, a larger wing will need lower pressure to attain the same skin tension (similar to bike tire pressure).
So they should all have the same ping frequency (and musical note).
Or am I wrong?
You gotta separate Rocket science from practicality.
Forget theory and "what should be".
Think only about sound of YOUR wing correctly inflated. And yes, it's different by air temps
