Actually, it is more meaningful than an absolute number - it is a "power index". Yes, it would be interesting to have more data, namely regarding populational basis and how the adjustment was made (a straight %, a deflating factor, log values...). If it follows a straight % (as it is simpler and the wording leads to believe), it means that each class has a Pc% of the total population (being each Pc% = (number of [lvl 70] chars of class "c" / total number of [lvl 70] chars) and the sum of all the 9 Pc% = 100%) and a percentage of the arena population above a certain bracket (Ac% = number of chars of class "c" with arena rating at or above X/ total number of chars with arena rating at or above X). Dividing Ac by Pc you get the index.Originally Posted by Gir
The main question is that how should population adjustment be taken into account for this, besides the "catch 22" already described. A better solution would probably [as sugested once by a poster and more or less included in one of the blogues that computes arena standings] be to take into account the actual distribution of a class - namely which % of the class has a rating above X and how that compares to other classes.
Btw, sorry for the dense post ^^
