2 days ago while I was taking test photos with my 5D3 to check AFMA I noticed that the battery was well below 50%. I remembered this thread and switched to continuous high. The sound was like 5 to 6 frames per second. This has been confirmed when I used the info button to check which pictures had been taken the same second. I counted 5 but this is an approximation (there is no tenth's of a second granularity). I repeated the test when the battery indicator was a little more than 10% and the sound seemed the same. So I believe that my camera behaves OK.
