CardioMagnitudeProduct = 0.23 StrengthMagnitudeProduct = 0.76 MWI = (CardioMagnitudeProduct + StrengthMagnitudeProduct) / 2 MWI => 0.495 |
Actual Workout Impact (AWI)
...
To do this, we calculate how much of the response has passed and how much is in the future. We do this for the cardiovascular and strength responses only.
The details of the calculation are explained herecan be seen in the POC but the outline is:
- Calculate the 'total response' for cardio by finding the time delta (in hours) where the response 'ends' (reaches 0.01). Do this for strength too.
- Estimate the area under the response curve between time delta = 0 and the end. Do this for strength too and add them together.
- Estimate the area under the curve between time data = 0 and now. Do this for strength too and add them together.
- Use the ratio between these two figures to determine the fraction of actual workout impact that has been realised and is pending.
Impact Credit Attrition
If the user does not complete a workout activity for 7 days, their realised impact credit starts to reduce.

Workout Response Type Fractions
...

CardioMagnitudeProduct = 0.13 StrengthMagnitudeProduct = 0.76 MetabolicMagnitudeProduct = 0.54 EpocMagnitudeProduct = 0.43 TotalProduct = CardioMagnitudeProduct + StrengthMagnitudeProduct + MetabolicMagnitudeProduct + EpocMagnitudeProduct TotalProduct => 1.86 CardioFraction = CardioMagnitudeProduct / TotalProduct CardioFraction => 0.0699 |
This data is used to create the workout response type pie charts.
...
In addition, we can combine the response type fractions and the AWI to show the specific AWI of a specific response - for cardio for example:

AWI = 0.385 CardioFraction = 0.0699 CardioAWI = CardioFraction / AWI CardioAWI => 0.1816 |
These breakdown figures are shown around the workout response type pie chart on the Workout Activity View.
