The AltAcc's sampling frequency was too low to accurately measure the acceleration at the frequency of the Hypertek motor.
What frequency did the AltAcc use? What frequency did they think was needed to handle the Hypertek motor?

Good point about the safety factor.
I cannot envision a zero risk factor, both as a flier or spectator, in this hobby, and it is something that I am very aware of.
That being said. As you put it, "with a little outlay (time and money)" I personally want to take what I feel are reasonable precautions, in an effort to mitigate what could be a regrettable situation.
This approach has saved me once from a stuck chute, so it works.Two full charges (or a plus sized backup) isn't a terrible idea.
Here's my redundant setup:
Main Altimeter:
-apogee charge, correct amount of BP
-main charge at X altitude, correct amount of BP
Backup Altimeter:
-Apogee + 1 second, BP+some (usually .5g extra)
-main charge at X-200ft, BP+some
We haven't been lucky, just playing within the extremely low odds of someone getting smacked. But with every failed flight that comes in, we move a little bit closer to an accident.
And finally, use your most reliable (or familiar) device as your backup. Thinking hear is the primary is optional, but the backup HAS to work.

Then use 2 of those...
