Look at the games I've played recently:
Play against a 1850 then back to some 1700s then get some 1610s then get mauled 3-4 times in a row by 1900s... How the heck is one supposed to get consistently better when one has to play such variable games time and time again??? I mean, what am I supposed to learn from getting torn a new a by some 1900s? or from bashing some low 1600s (I'm a 1700-1750 player...although it's hard to judge with such variable opponents...)? You might argue I could set my games up in the game browser, but again all I have to go off of is PR and HC level, I'm not going to minimize and look up every player I face in ELO... It's just very frustrating to face a pile of 1900s in a row as a 1700s player!
