That’s a very interesting idea, and I think you totally could. You run some benchmarks, measure the bit flips, and after enough runs you’d be able to say with a degree of confidence what your altitude is. I wonder though what accuracy could be achieved with this?

:D yes, although I expect you would need either a prohibitively large quantity of memory or a extremely slow rate of change in altitude to effectively measure it.

If the 96% every 3 days is true, you could approximate based on that. But it would be a really slow measurement.
