Here he is saying that he thinks the system is preventing him from climbing.
An FYI for if you didnt know, Cuthbert is a gold player, reach plat, dropped down to silver, yet thinks he is a GM level player. I think this is the reason he is making these kind of posts, he thinks way too highly of himself and the fact he cant get close to GM must mean the system is wrong. He has even stated before in a now removed post that he likes games without MMR because its easier to get more wins, A.K.A. he likes to play against people worse than him, not equal.
