Comparing efficiency ratios of building versus hitting

Kudos to Erraven for figuring out the building-prestige formula back in 2010. I took that information and added what I knew to it, and this popped out. Any information on how to improve this would be greatly appreciated.
Edit:you can just take the j out if you want a daily goal. I shouldn't have put that in there in the first place.

Very cool guide!

Yes erravens formula (and pres/unit per level) is probably the best post ever on these forums. You pose a very interesting idea about is it worthwhile to sustain a large army. Of course, I agree with you, entirely.

in my opinion you willl strike a balance, those near the top will do both.. maintain a largeish army (at least -30k per city). i manage to constantly train and use all my people and hit... but then i dont have coins to warp. the 4 people above me in the rankings all have coins, max build and can speedup there builds if they want to warp... i find its not a question of one or the other but doing both that will make you grow quickly
