Hi,
I created the sweetspot zone just under Z4 zone naturally named SS
In the general perspective overview :
SS zone appears in the power zones table.
SS zone don't appear in the histogram view.
So % values don't correspond between the chart and the table.
the issue seems to be the same in the workout editor :
SS zone appears in the chart.
but high values are in Z4 zone in the graphic panel and in Z5 zone in workout info panel
Bernard.
