What is Effort Accuracy

Effort Accuracy measures how well a structured workout is executed according to the plan. Simply put, Effort Accuracy is the product of the target completion rate and the intensity completion rate.

Example 1

Session is Run, Target is 30 minutes, and Intensity is Max Heart Rate (Aerobic).

If you run 24 minutes, the target completion rate is 24/30=80%.

If you spend 21 minutes in the Aerobic zone, the intensity completion rate is 21/24=87.5%.

Effort Accuracy of this structured workout is 80%x87.5%=70%.

Example 2

Session is Bike, Target is 10 miles, and Intensity is Power (200-320 W).

If you bike 7 miles for 25 minutes, the target completion rate is 7/10=70%.

If you spend 20 minutes in the Power zone, the intensity completion rate is 20/25=80%.

Effort Accuracy of this structured workout is 70%x80%=56%.

Example 3

Plan:

• Session 1 is Warm Up, Target is 5 minutes. 
• Session 2 is Swim, Target is 1000 meters.
• Session 3 is Swim, Target is 30 minutes. 

Actual:

• Completes Session 1 in 4 minutes.
  • Effort Accuracy does not apply to this session.
• Completes Session 2 for 600 meters and 16 minutes.
  • Session Effort Accuracy is 600/1000=60%.
  • Session Percentage is 16/40=40%.
• Completes Session 3 for 24 minutes. 
  • Session Effort Accuracy is 24/30=80%.
  • Session Percentage is 24/40=60%.

Effort Accuracy of this structured workout is 60%x40%+80%x60%=72%.

The calculation of Effort Accuracy is different based on the activity type, target type, intensity type, and session type. Please refer to the table below for more details.
