Fighting! I'm Doing It Wrong?

So just to reiterate I've come back to eRepublik from a break and am trying to get back into the swing of things. For the most part I'm getting on fine, even where features have changed and various wikis and so on haven't been updated.

But when it comes to fighting there is something that is confusing me.

Why am I getting so damn knackered?

On all help files I've found it says that each time you hit the fight button it costs 10 energy. I accept that these were written for beginers and very low level players, therefore when you level up the amount of energy used might also increase. But I just wish it would be consistant.

I have 500 energy, well, the capability of having 500 energy. But today in the resistance war the amount of energy used varied between 30 and 50 (always a multiple of 10). Is energy use documented anywhere for non-beginner levels?

Or am I just missing something really daft?
