The below report screenshot shows a value of 293 seconds for the time spent per visit metric. But when I manually calculate using the formula above, I get a value of 212 seconds. Which one is correct and why is there a difference?
Backend algorithm consist of some extra attributes also while calculating the metric values. Hence it is not feasible to compare the manually calculated value for metrics with the one calculated in the workspace. You will find some difference in both the calculated values.
