I've been known to shoot 1200-1500 in a day. It piles up at 9fps. On the other hand, in some other disciplines, I shoot more like 20 in a day. Rather than frames per second, its more like minutes per frame.
At a motor race, I may need to catch more than one type of shot of every competitor - perhaps 200 entrants. For some types of shot, one is plenty. For others, notably panning, I'll shoot multiple frames in a burst; then the next lap change shutter speeds to be more aggressive, shoot bursts of each car going past. Change again the next lap. That alone can run 800+. In film days I wouldn't have even bothered with the more aggressive pans, since even now I am only keeping one in twenty if the shutter speed is 1/30th.
In baseball, if you want a shot of the batter hitting the ball, you need to shoot every pitch, since you have no idea whether he hits this one or not.
On the other hand, I may take one shot of a landscape sunset to check DOF and other compositional issues, then wait until the light arrives at the state I want - and that could take 40 minutes. So two frames an hour...
