better matching around 820-1100 range

Players choose their skill level at account creation, the New to chess and Beginner are the only ones that start at or below 1000. The other three options are 1200+.
With the Glicko rating system players will quickly reach an appropriate rating; it doesn't really take many games either to get fairly close.

They won't be able to maintain a higher rating if their results don't reflect it. It doesn't take a long time for a player's rating to settle into a 200 point range. Certainly less than 500 games and probably less than 100.
