Efficiency index: how does it work?

To determine if a run is correct or not we can’t only consider if we make a clear technical mistake like a slip or not, but we have to consider even if we have kept a good speed throughout the run, so how can you determine if you’ve done it right or not in an objective way?

For that reason we have invented the Efficiency index that helps us to determine if a run is correct or not.

It works by adding a percentage to the best run we’ve made during the single workout or during a competition to determine till wich time a run can be considered correct, that is the Efficiency Time.

That percentage is a fixed value of 5% so for example, if my best time during a training session is 6.00 seconds, i will have an Efficiency Time of 6.30”, every run under that time would be considered a Correct run, every run over that time would be considered Not Correct, and that, as we said previously, doesn't mean only by technical mistakes but the runs has to comply with a time constrain.

The Efficiency time is strictly connected to the ability of the athlete to be consistent throughout the training and not necessarily about how fast is an athlete in an absolute way, considered that the time used to calculate the Efficiency time is the best of the session and not the all time best of the athlete.

The Efficiency time is variable during the training based on the best time of the session, so if you make your best time in the last run of the training, it could be that the stats will change even a lot.

After every World cup you can see on the stats about who have been the best athlete, the percentage of Correct runs and now you know how they are calculated!
