It's pointless to do that,  we might as well just use bayeselo exclusively.
    I actually considered making bayeselo the main page and removing the
other stuff.

But I think it would be annoying to get a certain rating and then without
playing any games come back a week later and the rating has changed.

I think incremental ratings are best and what we are doing here is making it
a lot more stable.

It will take some time for the bots to re-sync,   but that's ok.   As it
turns out Bayeselo rating seem to be higher so no bot will be rewarded for
not playing.    I think the rating pool in general has been deflating so
this will keep it stable.
