I don't see anything wrong with the cycle at all for the more advanced user looking to come in at the best condition on stage. I would be running something very similar for prep with some minor changes.
I like the idea of the cycle broken down into two phases aimed at initially adding more size and then following up with the cutting, hardening, and tightening up to the show.
