Even if it does shorten the life of my
engine, I will continue to practice it until I can execute it
flawlessly all the time.

(don't remember whose quote this was)
When exactly are you certain that you can execute it flawlessly *all*
the time? after 2 in a row? after 5 in a row? And once that's
accomplished in the present, do you assume you'll always maintain that
level of competency if you never practice it again?

I'm sure I'm probably over-doing it here, and I apologize if I sound
over the top. I guess I'm just not comfortable with assumptions even
though sometimes that's all we have.

Regarding your question "when exactly are you certain that you can
execute it flawlessly *all* the time?", the answer can be found in my
followup post: "We always learn something new from a new instructors,
always find room for improvements in our flying skills, and never feel
that we are good enough that no practices are needed."

Yeah, it was a rhetorical question. I realize the point you were making
when you said that you would continue to practice it until you could
execute it flawlessly all the time was that you would never stop
practicing it on occasion. I just wanted to emphasize that our
competency levels fluctuate and may not be the same three months in the
future as they are today. I know no one here needs to be told that.
