Streak based rating is flawed

[CombatEX]

Yea the point system still takes a long time to match against the right opponents. My friend doesn't have an iDevice so I let him play on mine (he made a separate game center ID). As you can imagine he doesn't play many games as a result. Currently he is 22 wins 2 losses and in Gifted league. His losses are to a Super-Titan who is currently in the top 100 (top 50 I believe) who he played in placements and a high masters player. Yet for some reason after beating around 10 masters players he's still in gifted and is now playing exclusively gifted players. Sure they are all high point gifted players but I watch him play most of his games and it's not even close... The guys he plays throw away wits left and right but for some reason he's still getting matched with them. In SC people like he could play 15 games and if they consistently beat Masters players they'll at least be playing all masters players if not beig outright promoted. In Outwitters he's playing Gifted players. It's pretty boring for him when he goes 50/50 against supertitans and high masters in friendlies but is still playing people far beneath his skill in league =/

The same happened to me in the beginning but eventually I ended up playing people around my skill. Still, even though the system will eventually do its job, it takes way too long to get matched with the correct people and for people who don't play as much it's quite annoying.
