You're right... It scales 50 points per square and it confused me a bit. It could be around 60 ELOs.

The difference is going to be clearly smaller with 64 cores and
I see no evidence that book at that time control is additional +50 elo.
Maybe book does not give much at long time control because the program can often find better moves by itself.
How I see it on 64 cores (we also don't know if these are cores or threads, since they don't say which machine they used, if it is cores Numa was not used, Large Pages were also not used):
SFdev vs SF8 at least 30Elo, hash up to 10ELO, EGTBs up to 10 ELO, large pages 5-10Elo, better SMP implementation of SFdev compared to SF8 for large number of cores (>32) 5-10Elo, Cerebellum book 30Elo against conventional engine, but against A0 most probably more, coz A0 is well trained for only small amount of openings, and good book would help SF a lot to get much more draws with black.
If you add all this together it is easy 100Elo if not even more.
No it doesn't, read again.
