Real quick, just a comparison of times from runners that ran at MIS and ran at various meets throughout the year. Kept the samples above 20 for each gender. This is not the way the ratings are generated, the ratings tend to use athletes ranging a bit further back than just the state qualifiers. But it should give a decent idea of how meets and courses ran throughout the year.
Positive numbers mean a course ran faster than MIS.
Negative numbers mean a course ran slower than MIS.
The adjustment for MIS will range from +17 to +25. The course, as always, seemed to run a little slower as the day went on. Usually, this is because of the course deteriorating, but my guess this year is that athletes’ times were affected by the increased temperature throughout the day.
