It is progressing, I *do* work around 2h/day on it. But balancing and finding an exhaustive and "fair" formula for unit cost/power calculations is an extremely time-consuming business. I am very sorry this takes so long, please forgive. But the original formula didn't work for Chariots, frelances, elephants etc. and had to be overhauled yet again. To quicken things up, I finally decided to program an Excel spreadsheet that relieves me of the stupid manual calculation.
Once again: I am a slug. I admit it --;
