The MoGo team has said that MoGo wins 62% of its games against a

Yes, I believe it does generalize on average.
This data matches my 13x13 study pretty closely, about 62% give or take
for each doubling. That is about 90 ELO or so. I have heard that
100 ELO is 1 stone which is what I was basing this on. But it's not
clear to me at all if that is true. So I can only guess that 4x in
Mogo is worth something like 1 or 2 stones or something between.

According to my experience with Go data, it is not possible to give the
value of one stone in terms of Elo ratings. For weak players, one stone
is a lot less than 100 Elo. For stronger players, it may be more.
Also, it is very important to understand that the Elo model is very
wrong, and Elo against humans has nothing to do with Elo against
computers (and even less with Elo against the previous version). In
games against GNU Go, Crazy Stone improved 200-300 Elo points in one
year. On KGS, this translated into an improvement from 2k to 1k.
