Welcome, Headmaster, and thanks for sharing that. If true, your insight is quite useful. One question though...

the end of each penalty period bears no relationship to the date of the next Panda update.

Why, then, do we seem to have the largest number of recovery reports at the time of each update? Yes, there have been some who have gained traffic at other times, but they seem to be the exception.

Perhaps the standard penalty times tend to be measured in months, so that the release date tends to roughly correspond to a Panda run?
