I think you wouldn't need to go based on G's.. I would just go on whenever the craft is at 70+ degree tilt.. which would indicate crash... granted only record those when above 10% thrust.
Yikes Bill.. seems like you should have burned up all the motors with that crash.
I think a crash count would be fun. Every time an accelerometer clocks over 10g's you get another tick added. I once hit the highest branch on the highest tree around, right after setting hold-alt, and my quad tumbled probably 100 feet through all the limbs, all the way to the ground smashing props and motor mounts and ripped out an arm. I found it in the thicket by hearing the motors screaming at 100% still trying to maintain altitude. I'd left the radio as I trek'd through the underbrush to recover it. (DOH!)
4 props, three motor mounts, a little super glue and it was ready in an hour. I couldn't believe nothing fried. Had to re-level the APM though, it was waaaaay off. hehe
Anyways, it would be fun if we had a crash counter. Short of running the quad through the clothes dryer, I can't think of a worse "crash" scenario for wracking up the crash points. lol
Isn't the flip of death a bad GPS? but yeah they should have log data.. and I wish the flight computers in general would keep track of two timers like odometers.. one being time powered up, and the other being time where throttle is above 10%... it would be nice to know how many hours I have flown one of the flight computers... which I could use as a way to know when to swap blades, motors, etc.
ESD.. Take a balloon... Rub it against your hair... Note the hair following the balloon like it is sticking to it. That is enough static to kill electronics.
Especially heading into winter, ESD is a big issue people should be more concerned about.
Often a source of phantom problems which can be hard, if not impossible, to diagnose!

Pssh! Yeah, and wait months for them to solve the Flip of Death because they don't log data.
Michael, I'll give you my KK board, then you can crash twice as much! LOL

See that nice fuzzy towel, a good material for building up a static charge. It might be ok, might not.
