A country is now considered a techer if it has at least 80% labs. Other strategies need at least 70% of their land to be covered by their primary buildings. This should resolve almost all cases where a player could reasonably consider an NPC country strategy to differ from the game's classification.

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?
