Not everything is data from a specific point in time and Panda may not be either.
example: your mid-term exams from 9th grade math class. Sure you can pinpoint the day you took them but in reality the results are timeless, they will never change unless someone reviewed the tests again.
Panda may be just such a website "score" and it doesn't seem to be one of the "continually re-applied" ranking factors.
