Overlap

Greg_Deckler  Wow, this for sure a variation of a problem I am trying to solve. 

I have some observation and questions based on this, that may help me solve my problem.

Here are my Observations

 - I see that when I select a particular meeting, the Overlap Card visual give me either 1.00 or 0.50 which is good. And by clicking each indivual meeting I was able to get the following result for each index

1 - 1.00
2 - 0.05
3 - 0.05
4 - 0.05
5 - 1.00
6 - 1.00
7 - 1.00
8 - 1.00

- I also noticed that when no meeting is selected, the Overlap Card returns 3.00

Here are my Questions

1. How do I get the Overlap Card to return the Sum of the Overlap result (5.15) when their's no filter?

2. How do I get the result to sum up correctectly when a few meetings a selected?

Thanks in advance.
