Send Z1 and Z2 as +-15%

Hi Alex, whats the meaning of the “send Z1 and Z2 as ±15%” Button in the garmin section?
Best, Chris

Hi Chris, it just makes it a bigger range. Since most people when riding at lower intensities would rather not pay attention to, it gives a bigger range so you don’t get notifications when you are out of range. Hopefully that makes sense.
