Thanks. Yes, that is indeed correct. I'll pass it on to my mate, he may have done his tests in the very cold Twizel winter (24/7 hoar frost for weeks on end) and camr to draw the wrong conclusion that it was to do with altitude alone.

Still, his observation remains, that only one brand was reliably crack-free, the others too close to the sound barrier to perform well in NZ-encountered conditions of lower sound velocity.
