Yes I know what your talking about. The first points adjustment I remember is when Eruption was on top and got about 9k points away from Laharl. Then all of a sudden he was not gaining any points on a win till Laharl got within 1k points. Then it went back to normal. What Nate did at the time was make sure 1st did not separate too far from 2nd.

Then later on I used Foxtrot and Echo to separate from the pack. I know foxtrot got over 420k points. Then Nate changed it again where once you got to the top your points for wins became very small. I think he put a cap also because I can't remember seeing anyone over 380k since that update.
