I apologize I do not understand where you are going with your recommendation. Attached is a portion of my data to better describe what I need to accomplish. Obviously there is a easy way to do this manual, but I am looking to automate as this is a big data set that is updated with new data monthly.
I need to average top 100 that have month = January and Site Status = Production
