Challenge #3: Running Averages

[BrianJohnson]

I am submitting a different output presentation.  To me, the goal was to present a 3 and 6 month average by those named columns and RM category.  When I look at the provided solution output, I didn't see that as the result and the RM category was mixed in with the various type of values.  

I'm presenting two displays in which I'd rather see the data.  Sorry....

Challenging target output to interpret and similar to some others I have chosen to display the output differently as I feel it is easier to understand.

My solution:

Here is the solution

The provided solution doesn't seem to match the brief as the 6m average isn't grouped by RM Category (though the 3m average is).
