It appears I need to tone down my enthusiasm a little bit.
Please, don't do that!
I am surprised that you consider the units' xml attributes as classified information . . . BUG uses them to tell you the power ratios up to 4 decimals.
Technically, BUG doesn't use them. What BUG does use is the power demographics values--available in the stock game's interface in the power graph--to provide the ratio. Yes, the game shows only a graph line, but you could use a rule to measure the graphs and do the division yourself.
BUG shies away from is showing XML values if they aren't displayed elsewhere.
