Ratings are only affected by how you shoot in relation to the rest of the field on a given day. Nothing about any previous rounds played on that course affects the ratings, nor par does not factor into it.
Here's my simple breakdown of ratings for people. If you'd like more information, look up information on a multi-player zero sum game.
Propagators are the people that set the ratings. They are people with a rating over 799. Each player over 799 has a bucket of points (determined by their rating). Those players also have a score they shot on that course. In what I think is a linear fashion, players give points to those who scored lower than them, and receive points from those who scored higher than them. These points come out of a person's bucket. So no points leave the game, but no points are added. In the end, these points are used to determine round ratings. So as you can see, ratings are simply based on how you played against the competition that day.
