JMAX and KMAX destroy altitude records!

 JMax flew on a J510W (AT) to 23,735 feet AGL, accelerating at 80 gs to mach 2.7.  This altitude is comparable to the performance of a conventional minimum diameter M motor.  The JMax is about the size of a LOC Aura, and I would guess not much heavier either (without motor.)

The equally tiny KMax flew on a K300 (CTI) to an astounding 31,643 feet.  This altitude is comparable to the performance of a conventional minimum diameter N motor.  Look how tiny those fins are!

Very incredible flights indeed! Although I would venture to say that the "Conventional" minimum diameter stats are one class off. Curt is blazing new ground in the performance rocketry field.
The sky is the limit!...or is it?

Would you say one class too low or too high?

I seem to remember good N rockets, that are not specifically designed for altitude, hitting around 30,000 feet. Like the Dr. Rocket modular rocket (now crazy old) or various rockets like the carbon yen. (Also old, heck I'm dating myself here.)
