Bug between mph of point vs graph ?

[ohgood]

when I click a point it says 112mph
but on the graph it's 72mph....

this was an imported track

Hello,
graph smooth values a little, compared to raw data visible in the detail of the trackpoint. But in this case, the difference is quite huge. If you share a track with me, I'll gladly look at the reason. But I expect, there is some high single peak that is simply smoother by the chart a lot ...
