A country is now considered a techer if it has at least 80% labs ignoring empty acres and cs. Other strategies need at least 50% of their land to be covered by their primary buildings ignoring empty acres and cs.

I have observed that this logic does not work well early in the round (when bots of various strategies have few built acres relative to their total land). For example on Coop: a 5539-acre Fasc Farmer with 2437 farms, 191 ICs, 240 CS, and 2671 unbuilt.

I also observed some late-game bots with unbuilt acres getting classified as rainbow. For example on Alliance: a 15092-acre CI bot today with 7456 IC, 240 CS, 7396 unbuilt.

Does it make sense to weight unbuilt acres a little differently in the classification logic?

Yes nearly every C/I in alliance classifies as a rainbow now

is it possible to update the code for CI bots in alliance to build up all their empty land as indies?

I have adjusted the strategy classification logic and all of the above scenarios should be handled better now.
