Max speed in Track Statistics is inconsistent with the speed on the chart

Hello,

Max speed in Track Statistics does not correspond to the max speed visible on the chart.

I am attaching a GPS file as an example. Max speed displayed on the main statistics screen is 36.4 km/h.

On the chart the highest peak is at 31,6 km/h. Trackpoint 22 (the darkest red with a speed coloring) shows only 32,2 km/h. It is a measurement at <time>2019-09-30T13:04:07.000Z</time>.

It would be nice to know the truth.

I don't think the reason for that is an "altitude jump" as it is in a range of 1 m (water surface).

Noticeable, around that point the frequency of measurements alterated; at 13:04 there were measurements at seconds 04, 06, 07, 08, 09, 11, 13 and so on. Perhaps, the speed calculation and determination of the maximum was confused because of that?


Thanks and best regards,

Alexander

Hello Alexander,

this is correct observation and point on the problem we did not yet perfectly solved. Value in statistics is the correct measured value. In the chart is applied a small "smoothing" mechanism that reduces such some peaks and makes the chart a little more ... well, smooth.

Hello Menion,

thanks for clarification! In fact it's quite good that the chart is smoothen. Now I am sure that around a chart peak it was a truly high speed, not just a measurement surge.

What I am personally missing is a direct jump from the overview statistics to the appropriate extremes on the chart. For instance, if I press on "Max speed" on the overview, I get the chart displayed with the focus set right onto the point with the maximum speed. The same for altitude etc.

Thanks and best regards,

Alexander

Hello Alexander,

oki fine, thanks for understanding.

Click though item in the dashboard to chart itself: I also personally few times wanted to see this value on the chart, so agree it is missing! We will be reworking screen with track detail during the next months so I'll keep this in my mind during that process.
