From a roleplay standpoint, I think that idea that you are closer or further from transformation makes a lot of sense. I'm not sure the numbers work to simply make it a percentage maneuver, but if it's some kind of steps on a track, then slipping closer to transformation is when you need that Calm Self, you want to start meditating (if circumstances permit!), etc. And you might be able to deliberately transform but you have to spend some time really working yourself up.
