I played French horn, too, and have always tapped with my right foot.
Didn’t that hurt? Maybe my braces had something to do with my aversion to being rapped in the mouth.

There’s many layers to the question that haven’t been asked.
Do you tap with your dominant foot or non-dominant foot?
Heel up and down, or toe up and down?
Straight up and down, or do you add twists or sideways movement?
What tempo? How fast does the music have to be to start the tapping?
Do you tap only consciously, or does it start without any thought on your part?
I had to work really hard on swaying. There was one concert where I fastforwarded the video and it looked like I was going to get sea sick.
