Rating changes to quickly after each match.

The K in the rating formula is too high:

1. Players often play both sides consecutively against the same opponent. If they both win 1 game, it is not advantageous in term of rating for the one won the first game.
2. A bad luck streak will introduce large ranking swing which can demotivate players to continue the league.
3. The spread in rating between the top and the bottom of the ranking is already quite large (350+) although there aren't that many games played yet. The players at the top risk a lot of rating to win few points. There is an incentive to play less or be more selective about the opponents.

Suggestions:

1. Reduce the K from 32 to something between 8 and 24.
2. Consider 2 consecutive matches against the same opponent with opposing sides as a single match with a double K. Use the official prestige points system to determine how much rating each players gets.

1. KFactor is currently 3-tiered (16, 24, & 32). The tiers break out as 32 to start, 24 when you're rating is >= 1.3125 the initial board rating, and 16 when your rating is 1.5 * the initial board rating.

Once you pass these thresholds, you stand to lose less ELO. With a 1500 base rating, you're K will drop when you hit 1967 and 2250.

1. In the context of Netrunner, that requires a 2 match set which limits flexibility in terms of time commitment. Many find the current Prestige system flawed (including myself). This is something that we will discuss at some length after the league is over. I may end up going in, but I think the odds are stack against it.
