About Target Weight Date Calculator
Zone targeting for Target Weight Date measures the current value against a target and draws an acceptable band around it, showing whether the result sits inside. Health goals are rarely exact numbers, so a tolerance band is a more realistic way to track progress.
Formula
Target Weight Date
Share = current / target x 100; band = target x (1 +/- tolerance)
- tolerance
- How wide the acceptable band is
