Counting steps when moving hand

I noticed that from the beginning. Regardless the Firmware

For me is the same. But when i actualy walking when mowing the lawn there is not one single step. You know, the Garmin way  

Just how should the watch be able to detect steps when you are holding a lawn mower?

I believe the MEMS gyro (and/or) accelerometer devices in these products are extremely sensitive. They would absolutely be able to detect forward motion and cadence from your steps, even with your hand resting on the mower handle rail. Whether that detected motion fits the profile to count as "steps" is more of a software calibration issue.

Imagine home improvement: hammer drilling two holes do account for a double marathon

Here are the same findings and a possible solution when you push a lawn mower or a stroller, put the watch in your pocket.

uhm, there are other home 'improvement' activities () that generate several marathons.

Hehe - they know what you do in the evening when being alone at home :)
