Not when you're doing panning IMO. When you're panning, you mostly move a certain set of muscles in one direction, instead of constantly moving a complementary pair of muscles in opposite directions to hold still. Same reason you'll be more likely to mini-wobble on straight-line than at turns in balance-sports. This way, high-frequency vibrations can be substantially reduced. The problem with panning using down to 1/60th shutter is that you have to pan really in-sync with the moving subject for a blur-free result. I recommend practice before event day if you run such low shutter speed.I have read 1/60th is good also. I thought hand holding 1/60 at 200mm was a bit ambitious.
