i reported my GRE scores and percentages based on...

...the very first score report i received in the mail in the spring of '07.

i sent out my GRE scores and reported my scores and percentiles on many of my electronic applications.

after i had my GRE scores sent out i also got an extra copy mailed to myself. and then i noticed my percentiles have gone up by a few percentage points over the past year and a half! on one hand it makes me look better, on the other it makes me look like i filled out my applications wrong.

so do i now have to go back and contact all of the admissions offices and have them fix my submitted application for me? or is this kind of thing common?

obviously my scores remain unchanged and thats probably more important, so are graduate departments aware of fluctuating percentiles?
