It stands to reason that the older you are the more powerful you become simply because of a few reasons. With age comes experience, if one lives through that experience one gains knowledge. Then there is what amounts to lifetimes spent learning Zanjutsu, Hoho, Hakuda and Kido (depending on the person) that having mastery puts them on another level. I think the most important thing is how one nurtures their Rieryoku and on what level its at the first place. So its a bunch of different things that come together to make someone powerful but yes age is an important factor in making that happen.
