Find my approach as reference below and stored in attached workbook version 10.5 located in the original thread.
1. Score: [Succesful]/[Total]
2. Rank: rank(attr([Date]),'asc')
3. Average: window_avg(sum([Score]),0,3)
4. Drag the required objects to the indicated loations and set rank to discrete and show Performer Filter
Hope it helps

Hi Norbert! Thank you for the response. I would say this gets me 99% of the way there! When I do it exactly the way you have laid out, I get the same result, however this result is based on Exact Date and I am trying to do it on Month. I apologize. When I apply to Month, I get a lot of nulls and every so often a date gets ranked (keep in mind I have tried this the way I have copied, as well as using the restart every performer option).
