I only just saw this. i think there's a small mistake here:

His tank with 1 speed only has a 80% chance of hitting my Oshannus with calculations being as follows: (9 speed Oshannus - 1 speed Mycelic Infantry) * 10% = 80% miss chance.

Shouldn't that be 20%?

Thanks for the update, btw. Bookmarked it for future use.
