Greg_DecklerI'm wondering if I confused the issue by calling the column I'm trying to sum "time"?

I've editted my post above.

My issue is when I sum March 2020 I need a formula that uses (for example) the first line for Object D (1.00) and when I sum April 2020 I need it to use the second line for Object D (0.80). I don't think time/duration plays into it?

Now I'm confused, I done understand how you are getting from the sample source data to your desired results.

      OK, spewing numbers at me <> helping.

       

      What is the logic going on here? Why are those numbers included with March 2020 versus April 2020, don't make me try to figure it out, just tell me. The only one that makes sense is July 2019, there are actually 7 rows wtih July 1 2019 as a Start Date. March, I have no idea why there are six March numbers to sum up. There is only one row that matches March 2020. Same for April. So why the magical 6 numbers?

        Once an object starts, the ObjectAttributeX counts for every month thereafter until the end date.
        For March, all the lines that started 7/1/2019 count towards the March total, except for lines 3 and 8 because they have end dates prior to 3/1/20.
