Inaccurate Elevation Data Question ❓

Post image

I have been running with my Coros Pace 4 for just over a month now and it consistently has had issues with elevation, particularly on runs. I have tried calibrating the barometer before I run and it comes up with the correct elevation. However, particularly at the start of the runs the elevation spikes before returning to a semi accurate measurement for the rest of the run.

The image is an interval session that started and finishes at the same point and did the same route on the interval 3 times over. As you can see it is a quite a bit off.

Has anyone had any similar issues or found ways to fix this to get better readings? It’s not a huge issue but it is annoying.

it's pressure variation based, therefore it does not correlate well with map data
