It still adds entropy. You're thinking of uniform entropy vs just entropy, but the former is easy-ish to produce from the latter, for example by using hash func

It still adds entropy. You're thinking of uniform entropy vs just entropy, but the former is easy-ish to produce from the latter, for example by using hash functions. Also, it's obviously a stunt - you are probably much better off measuring decay of trace amounts of natural radioactive isotopes. But it is not without merit.
