This was a tough one - interesting to learn about the imputation tool though

Probably a more efficient solution, but this one works!

Definitely did this the hard way! Like others I was beating my head against the wall on the 6 month averages once the HP group changed.
Duplicated effort way too much but was a good practice in repeatedly working with the multi-row formula and a great reminder at how awesome the transpose tool is once I started reviewing other solutions posted!

This was an interesting challenge as I haven't had to do running aggregates before.
I used the brute force approach to get it done, but I had to believe there was a more elegant solution that would allow only two multi-row formulas.
Now I see how this kind of problem benefits from pivoting the data.
I also learned about the quirks of the Impute Tool in how it can introduce seemingly random new fields out of nowhere. (Turns out it's because of a background cross-tab.)
I think my solution is successful, though I'm not sure how the given solution produces so many decimal places.
