Let us mourn the death of AsmFish

It is now essentially the same strength as Stockfish.
Now, people will say that the graph is simply compressed because of the longer time control. I doubt it. SF8 under the same new conditions has the same strength or a wee bit higher (probably not discernible under the error bars).
No need to bother with AsmFish anymore.
It's dead or dying, and now it's hit the floor.
I think something bad probably also happened to SF also between June and August. Just Elo compression due to more time? Why then, is SF8 not equally affected? And the time control change was not very dramatic (IOW, we do not see this evil compression effect even between CCRL 40/4 and 40/40 a ten times increase in time control -- It takes huge hardware and cores to do that.). It is also possible that the book is defective, and that could be the full explanation for the problem. If you have a won position in a book exit, and then the weaker and stronger engines play both sides reversed, the weak engine gets a free win from that. But according to my understanding, that book was checked very carefully. So the bad book seems an unlikely explanation.
I would be very interested to see if Cfish has been immune to the plummet.
