Change in calculation method
As the new FEI rules for assessing heart rates do not take into account the way heart rate monitors (cardiotachymeters, electrocardiograms, etc.) work (average rate over a period of time with the minute as the unit of measurement), an incident in the last 15 seconds (45 sec to 60 sec) may unduly eliminate a horse that has been stable up to that point.

We have therefore added a calculation of the period of time from zero to the moment of display at 15, 30, 45 and 60 seconds.
