Thanks, @David_Jerome and @PratheepArunRaj . Even though I remove the department dimension, the numbers still don't match up. Sorry I can't share the screenshot at that level. I also used Total Seconds Spent / (Visits - Bounces) to verify but got a different set of numbers. There could be some kind ...

Try to figure out how Time Spent per Visit is calculated, but I found thisWhen I bucketed the metric, I found that it might even lower the lower boundary of the interval. For ex., for 5 to 10 mins bucket, the Time Spent per visit was 2.25 mins. this deosn't make any sense to me. Could anyone help me...
