OK, the statistics in cyclic mode with the -E option is completely wrong but a possible fix is likely to affect the whole of cyclic processing, so I just cover the hole with your patch and leave the statistics problem as a known issue at this time. I would revisit it when I have time. The patch was applied to the devel branch.
