How do you split the "Pretty Boy" and the "Money" eras in Mayweather career?

Ok, the general consensus is Floyd prime was divided in like two, but, when started one and when started the other in your opinion?
I think, despite still scoring some impressive KOs (Hatton and Mitchell), you could consider most of his welter/superwelter work as "Money". He became more flamboyant with his persona outside and more focused on his defensive wizardness.
You got a couple of stinkers at the lower-weights going to the distance but still, until superlight-weight at least, he was "Pretty Boy" imo. Being still very defensively responsible but getting caught more and letting his hands fly with speedy combinations that carried lotta of power which dissipated during the weight-climbing. Gatti and Corrales being at his highest powers during that run and Canelo being the most stellar example of "Money" (which ironically I consider his last performance before the end of his prime).
