|Total # CRIs performed||146||Completion rate - HR up by 4 bpm over resting HR||58% (33)|
|Total # horses out of check point||147||Completion rate - HR up by 8 bpm over resting HR||43% (23)|
|Overall completion rate||59%||Completion rate - recovery HR 48 bpm or less||62% (74)|
|Completion rate - no change in CRI||63% (90)||Completion rate - recovery HR 60 bpm or greater||44% (25)|
These figures point out the positive correlation between a passing CRI and the probability that the horse will complete the ride. This suggests riders and veterinarians should watch horses more closely with a questionable CRI as the statistical odds of completing decreases with a CRI that does not return to resting heart rate.
(Editor's note: It should be noted though the CRI is a very valuable tool in assessing a horse's ability to continue, it should be just one of our tools that we use as part of the whole picture to evaluate the horse's ability to continue and not used solely on its own.)
