I think everyone would do well to remember two things: (1) mostly what ratings are used for is to move lower rated amateurs along in the skill based divisions to reduce any bagging that might be going on. If you aren't a lower rated amateur who wants to bag, it does not matter if ratings are a rough measure. They beat having nothing. (2) One less accurately rated round is not going to have much effect on your average if you play as few as five tournaments. Suppose the wind came up and the course played 2 throws harder for the people with late tee times. The people with early tee times might get an extra 20 rating points for that round than they deserved. Average that in with nine other rounds and it will swing their rating by two points. And here is a bonus third thing: (3) If you regularly play tournaments with consecutive starts, those kinds of effects are going to average out. Unless you have truly ****** off God, in which case you have bigger worries than your rating.
