I disagree that some minimum number should be used; just a time period.
1) "How many games since then" is indicative; I think it may be even more indicative than the ratings system, in that, it's not subjective and to an extent, the number of games is in the player's control.
2) If a timeperiod expired the first 50 ratings, say, of a player who has only played 175 games, you still get an average based on most recent games.
3) If a player is only playing a game or two a month, keeping the "newest 200" means several years' ratings are still showing up, which defeats the idea of expiring ratings that may no longer apply.
At the minimum, however, ratings by those nicks that have been perma-banned, should disappear.
