I always think it is better if the student practices perfecting the maneuver, than if they are just practicing the manuever. Sounds like you are doing that. If you are devoting most of your energy to making the maneuver go well, i.e. flying, and not practicing the procedure, then you are being more efficient. It may seem like you aren't flying better, but the more you can practice perfecting the maneuver, the quicker you will attain the level of mastery you need. Remember that even 5 minutes spent prepping on the ground can save you up to 30 in the air.
