Identify different sessions base on multiple criteria

Hi v-henryk-mstf and thanks for the reply 😃

I've tried to recreate the table I have, I cannot post ithe exact table since there is data from the company. 

The column Visits is the expected result yes. The time spend in the page, as you say, would be the last time minus the entry time.

And the change in the visit would be affected by change of the user, also if the user changes the group page; what I mean is that I have the main page (project for example) and then the different subpages under it (like projectmain, project build, projectcanvas...).

Last, if there is a big gap in the times, say I have same user, same page, he starts at 17:30, and the next time is 19h,  I would consider this as another visit. 

Hope that makes sense.

Thank you so much for your time ^^
