What is the Mastery Score and is it laggy for you ?

By Mastery Score i mean the number that is shown in your champ collection (i cant take screenie xD) and also is it laggy for you, because for me it kind of is.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
