If you notice power drops when looking at your data in PowerCenter or the Stryd mobile app, you can stop automatically importing your data from Suunto app and upload the Stryd data directly with the Stryd app on your mobile device. You will get all the Stryd metrics but miss out on HR and GPS data.

You may see many power drops that each last just a second when you look at your data in PowerCenter. These drops are not present when running with the watch or in the Suunto app (data below from Suunto Ambit 3 vertical without HR monitor):

Our own testing has shown that disabling GPS improves the Ambit watch performance (Ambit 3 Vertical without HR monitor):

This is a Suunto issue, the watch simply does not record any data during that one second:

You can see that there is no power, no speed, no altitude, no temperature, or run cadence. You will not see this drop in the Suunto App as Suunto will filter out these points in their graphs whereas Stryd simply plots each point.

You may see power drops for just a second when you look at your data in PowerCenter. Below is an example, at 2:00 minutes power and pace are 0.

This is a problem with the watch. At that point, the Suunto watch is not saving any data into the FIT file. Here is the data from the FIT file (screenshot from Golden Cheetah):

You can see that there is no power, no speed, no altitude, no temperature or run cadence. You will not see this drop in the Suunto App as Suunto will omit these points in their graphs whereas Stryd simply plots each point.
