I once memorized the modern stunt routine while on a 5 hour flight from Honolulu to San Francisco. Repetition, over and over, for 5 hours ensured that I would never make a mistake in pattern sequence.
I used to take every opportunity to practice the stunt schedule, even in poor weather" cold, wind.
After I quit competition flying, I now carefully choose flying conditions, opting only for warm days, and calm winds. It is now a lot more fun to spend a day at the flying field. I can now make an awful pattern, and not punish myself for mistakes. Who cares?
There is no more any "practice".
