Is there a polite way to point out that an instructor is rushing through?

I started at a new studio because I moved across town and my schedule wouldn’t allow my normal classes at my old studio. I’d been going there for 2yrs, 4-5x/wk with several different instructors.

It was a flow/mobility class. The instructor was going so fast that it didn’t feel like “flow”. She would tell us to go slow and then immediately move into the next step so no one had time to be slow. She also took time on the right side/clockwise, then rushed through the left side/counterclockwise.

If I have her as an instructor again, should I say something to her after class or just avoid taking classes with her?
