What you've added in F.46 is a good start, but as a suggestiom, instead of disabling one thing at a time, try disabling *everything* and then see what you get, and then enabling one thing at a time. The best thing is if you can get to the point where the amount of entropy is close to zero. Then as you add things back, there's a much better sense of where the unpredictability might be coming from, and whether the unpredictability is coming from something which is fundamentally arising from something which is chaotic or quantum effect, or just because we don't have a good way of modelling the behavior of the L1/L2 cache (for example) and that is spoofing your entropy estimator.
