DIST UNPROVEN

Fires when 1 or 2 (but not 0) starts at today's distance appear in the last 10. One or two data points provide some information — you can see whether those results were competitive — but the sample is too small to be statistically reliable. Distance suitability is most credible when established over 4 or more tries. DIST_UNPROVEN signals a horse that has some distance experience but not enough to be confident about how it will handle today's trip under varying conditions.
