How to add average column to timewrap table for multiple fields?

[michaelsplunk1]

Hi there!

I want to add columns to this table that I copied from the docs about timewrap. I want to add columns that have the averages for each field (accessories, sports, strategy, etc.) across the timewrapped columns. Basically, a column for the average of ACCESSORIES_S1, ACCESSORIES_S0, etc., and then a column for the average of SPORTS_S1, SPORTS_S0, etc., and a column for the average of STRATEGY_S1, STRATEGY_S0, etc.

Additionally, I eventually want to use these averages as a trigger for an alert when the counts on these (i.e., accessories, sports, strategy, etc.) surpass the average. Long story short, I have an arbitrary number of fields, with a count on those fields, and I want to alert when the count on those fields exceeds the average, without having to set up multiple alerts for each field because I don't know what the fields are going to be ahead of time and the field names can change. 

@mattymo your multipart article on timewrap and Cyclical Statistical Forecasts and Anomalies has helped me so much, can you please help me on this application of timewrap?

Thank you!
