As in any real dataset there is noise among the observations. Systematic differences from pre-test to post-test are what you're hoping to discern. If PR courses were systematically faster one year than another that would bias the results.

Among the top 2-3 bands that would probably be the State Meet course - I would think more of those kids run their PR at NTR than any other course. Last year the state meet was run under near ideal conditions which would lead to larger drops in typical PRs for those bands.

Statistics rarely yield much of value in making precise predictions for an individual, especially when there are so many variables affecting the outcome.

At best this provides an estimate of reasonable expectations for typical changes for each band of individuals.
