Excuseth me, I am neither an flight-instructor nor pilot.
But I've to say that there is "talent" or not. I did some racecar-driving where the observer (not instructor) just said: ok, just do it.
Given, it's easier at FL0 - but then I had pilots as SLF in my car, puking over possible G-forces on FL0
OTOH I was SLF for those very pilots and they told me "ok, now show me your 'sensitivty' at the yoke" - did as told, and
the only response was "height not 100%, but hell, you never flew before?"
Plain number-hours-of-training doesn't mean ****. A tad of talent is needed.
