K factor should decrease over time #12

Keeping the k factor at 50 make the variance too great to be representative of their actual skill after a certain number of games. Maybe reduce k factor every 25 games with max reduction to 15? Compare to US table tennis and US Chess Fed.

Agreed! Most implementations of ELO ranking systems that I've seen do this to some extent.
