For maximum FICO score you ideally want every card except one to report a $0 balance and one card to report a $1 balance (some issuers will forgive a balance of $1 so you might have to use $2). You do this by paying down the cards before the statement generates. Once the statement for the $1/$2 card generates you can then pay it off.There is no need to revolve a balance. In fact if you pull your credit reports it does not even show if you are revolving a balance. If you would like to see what data is in a credit report you can obtain a copy for free.
If you are interested in how FICO scoring works there is a lot of information available on various forums. The best resource I have found is on https://creditboards.com/. The FICO algorithm is proprietary and they do not disclose it, but through experimentation people have managed to reverse engineer quite a bit of it.
