I've noticed that when playing new players there seems to be a minimum rating increase of +1 regardless of what rating someone already is.
Examples:

This seems to invite rating abuse as someone can play hundreds of games against new 1500s and end up with a hugely inflated rating.
I'd suggest that at some point the increase for a win should be +0. The above examples show this doesn't happen for a difference of 900+ points, but I'd suggest it should be true after 500 at most.
