• Percentage on a station's page

Hey guys!

On the CheckiO map, the number next to "Elementary" says 100, which I presume is the total number of points scored for that station. When I enter the Elementary station's page, however, it says 91 % next to its name. What does this percentage indicate? Is it my progress for that particular station? Or is it the percentage of the total points available that I have scored so far? Or anything else? Furthermore, on my profile page, under Elementary, it shows 55 and 91%. Now what's this 55?
