It says around 60K since mid-August, which is about 1666 rolls of 36 exposure film. Would I have shot that much back in the film days... no, because the cameras were typically 5-6 fps. Also, a significant portion of those images were shot available light in hockey arenas where (for this specific client), if we were back in the film days, would have been shot on strobe at one frame every second or two rather than ISO 6400 at 10-12 fps...
What I'm finding with the X vs. the 1DIV and III is that my productivity from sports events has increased about 30-40% in quantity. While I haven't analyzed it closely, I would say the keeper rate (technically acceptable images) has also increased, but in the 50% range. And I don't think my technique has improved that much in one season. It's simply the higher fps rate captures a broader selection of images and the better AF performance results in more technically acceptable keepers. I do feel this results in a better selection of final best images as well.
