i looked at the elo formula a while ago and noticed that once a player is past a
certain rating(2500 i think), a lower constant is used to adjust your rating.
which means theyll get fewer pts for each win. so there's also a mathematical
reason why the difference in strength between 2500-2800 is greater than
1700-2000
