This is my user flair badge:
I have 468 rep points in meta.stackoverflow and 533 rep points in stackoverflow
I don´t understand what is the 760 in the badge.
I guess the answer is really simple but I CANT get it!!
You've gained quite a bit of rep in the past 24 hours. I'd peg you around 350 + 400 total rep yesterday. The flair doesn't update that quick, the images are cached. You should see it jump up when the cache gets refreshed, probably once a day.
See if it adds up to that... If it doesn't, I am out of ideas!
