Rolling Averages

[mahouser]

I'm trying to calculate a rolling 8 hour average of a dataset that is based on a certain ranges of hours during the day.  The rolling average is based on the next 7 hours versus the last 7 hours of the data set. 

[Stachu]

can you share the sample from your data table?

Here is a 24 hour reading of Ozone Detectors at 2 different locations:

I need to calculate an hourly rolling average for Ozone over an 8 hour period (Time + 7 Hours Forward) per Site.  I'm hoping to do this in DirectQuery Mode.
