A Slight Problem About Rep Button

Nothing big, but when I give a +rep to someone, the one I +repped got +2 rep at once.
And yes, no one was giving him any rep before I +repped him.

Is there something wrong about the rep button?

or maybe I'm just too awesome that I can give 2 rep in a go

I'm going to guess that someone else probably repped them before your page refreshed to show your +rep.

It was probably just lag or something since I've triple posted before.
