Charge Partitioning

I was practicing a bit with a few general techniques with Alex and I read about charge partitioning. I have a few questions about how it is implemented in the game.

-Is there some sort of time limit between partitions before it resets itself?
-Is there a time limit to how long you can partition?
-Is there a limit to how many partitions you can make before it’s ineffective?

Thanks in advance to those that care to answer.

P.S. - Might sound like a stupid question, but maybe a little guidance on getting my signature to display as links would help too
