1/10, got me to respond.
With dynamic sports and an all-day event, eg of 50 rally cars passing by from morning to night, you can create a lot of images without even trying. I can come home after a day long event with 1200 shots or more to throw into Lightroom (after a preliminary culling scan with the excellent
FastRawViewer).
There have been several days where I have had to change batteries mid-day, so the more shots per charge, the better. Some lenses (eg my Sigma 70-200 HSM II) also seem to help run the battery down quickly if you use them a lot. So it's not just spray and pray.
