Your looking into it to much. Try your tests with a 3v3, 1 pesent unit as general for both your army and AI, and then 2 units of your choice (knights) and 2 for AI (pikes) then see how different your results will be overall. Becides i wouldent draw any conclusions now when there going to patch this thing up by the end of this comeing week.

On a end note, i will say that the loose formation seems to not have any penlties, because if you do the same type of tests with 2 handed units (german oines) against pikes, they will butcher them compared to if they were in tight formation.i suppose this has more to do with the envople idea, but i think units in loose formation are unweildly, and vunrable to a counter charge by wedged or units in tight formation, but i cant conform or deny that, just based on some battles i've had in the campagin.
