CCleaner clean reports

I am confused, as when I press the analyse button, it will report x amount of trackers and y amount of junk to be cleaned. I press the clean all button, and it will bumble its way through the process, then it will announce with glee that it has cleaned a higher amount of trackers and junk than it had originally discovered! Explain that if you can?

There may be a rounding difference for parts of a MB, and the files to clean may grow between the analyse and the clean.

ie. analyse may show 44 MB, but clean show 45 MB.

If you are seeing larger differences then could you provide some screenshots?
