Summary page showing lower than actual percentile

Just downed mythic dragons with my raid. On the logs of the kill itself it shows me at the 60th percentile but when I went to my summary page it shows me under 50 for some reason.

My summary page: http://puu.sh/setyo/718e704a81.png

Mage rankings: http://puu.sh/setRW/2d61294e8d.png

Unsure what to make of this.

Those are two completely different things. Statistics is all parses. Rankings is best parses. You can actually compare against statistics in the character page as well (it’s an option from a dropdown).
