Watched a new guy test a pitot static system with the old push button box while I had the digital ADTS hooked up, and the readings did not match at 35,000 feet simulated

The old push button boxes are notorious for drifting at high altitude sims, especially past 30,000 feet. I've seen them read a few hundred feet off when the seals start going bad, which is probably what bit that guy. Have him check the case for leaks and zero it properly before you trust any comparison, those boxes need a good warmup too. The digital ADTS is almost always the one telling the truth, so I'd lean on your numbers over his.
