intervals does not do that.


If you extend that to every hour, be prepared to carry one wing for a while due
to weight imbalance. It's not dangerous; just an annoyance.

It largely depends on the plane. In my old C140, you couldn't even tell.
In my friend's Tripacer, it's obvious. In a Grumman Cheetah, it's
noticable a little. In a Cessna 180, you can hardly notice.
