I was ready to post my updates to Tunguska, so it's nice someone already did it, thanks!

It still pretty weak, but certainly ~100 ELO stronger than the previous version.

I;m sure it will keep improving.

Yes, it seems it jumped from 2141 to 2509 in 40/4, which is way above my expectations, so I better wait to see if that is correct

It is going to lose some Elos probably, up to now it has played against much weaker opponents but that will be corrected.
