It was 931, not 831 on that practice round. Scorea were high because practice rounds were going for 285 seconds, more than double the standard match time. Fast robots got in lots of laps, and there were quite a few hurdles, too.
Scores posted on Friday should give a much better indication.
BTW, the St. Louis field has a couple of very fast racerbots -- the well known 148 which our refs have christened "Super Roomba", and the local favorite 1098 which looks and runs like a little Ferrari.
edit: check out some video of 931 in action. A launched trackball can cover some distance, and might just get loose.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
