To the wiseguys, yes I in fact do hold altitude pretty closely when
flying.

Do any of you have similar odd real life habits you think enhance
safety?

I fly at the assigned altitude, period. *I put my trust in the
controllers and would hope that the PIC's sharing the airways with me
are just as trustworthy (and professional). *Someone that thinks
deviating from an assigned altitude by as much as 100 feet (plus or
minus) is "OK" should spend a few hours with an instructor that's
going
to rap your knuckles with a ruler when you try pulling something like
that in the name of "safety".

I many jets, it's nearly impossible to hold +/-100 feet for any
extended period of time without the autopilot.


Bull****.
