I've noticed that there hasn't been a mega Prime discovered in a couple of months (at least my read suggests the last announcement was December 7, 2021). I'm curious if anyone has looked at the overall frequency of mega Prime discoveries. It would need to be normalized somehow by the amount of computing effort directed at a given problem (or problems).
Just curious if there's any sort of pattern, and I lack the mathematical chops to figure it out for myself. Thanks!
