Hi,
I would like to know how to calculate the metric "Time spent per visit (seconds)".
In the Adobe Experience Cloud Help I found this table:

Thus the correct formula should be:
Time spent per visit (seconds) = Total seconds spent / (visits - bounces)
We tried to use the formula in the example below:

According to the Help Center formula we have to calculate it like this:
Time spent per Visit (seconds) = 153,26 / (3,914 – 2,964) = 161 seconds
But in this case the declared metric shows 39 seconds. I can imagine that this is the result of the following calculation (without considering the bounces):
Time spent per Visit (seconds) = Total seconds spent/ visits
Time spent per Visit (seconds) = 153,26 / 3,914 = 39 seconds
Does anyone have an answer to this circumstance? Which formula should be used here?
Thank you for your help.
