Beast mode calculation: Last compared to past average?

Options

Hi - I'm trying to figure out the calculation to identify an action needed. I know how to do in Excel, but still learning the SQL / Beast Mode equivalent.

I have a count of total items. If the count of total items from last week is 20% less than the average count of total items from the past 6 weeks, I want it to be marked somehow.

Thanks in advance for your help!

    Is this to identify current state or would you need to know historically if the action was needed? If the former, I think you can use a fixed function in a beast mode to find the latest 6 week average and compare that to your current week count. If you need history, I think you'll need to use MagicETL to group by each week, then lag the previous six week totals so you can do the math to find the specific prior 6 week average for each week.
