Hopefully it is still much stronger in reality.   But I think your
opponent in this case is too strong to really get much of a sense of
what is happening.   

If Mogo really isn't improving against humans but is improving against
other Mogo's and this is a substantial effect,  it means something is
wrong with the algorithm - I would guess this would indicate that Mogo
is too selective.

I feel your pain - there is no easy way to test any of this without more
power yet.    If you need a network of workstations to test a single
processor program,  then you need a several networks of workstations to
test a single network of workstations!
