I wouldn’t go as far as to “report” the remainder advantage from battle to battle as that would introduce unfair behaviours i’d say.
While it would be interesting to be able to “game” the system and “boost” one particular battle, it doesn’t sit well with me to be able to “pull” power from one land battle onto a naval battle for example, where that power is much more impactful.
Or doing the same to go for an air raid on, say 2 infantry, while knowing they’re at -4, so you know for sure you won’t get hit back.
