Solution attached!

Note: the example in the comment box within the workflow shows an incorrect calculation (233 vs 230), as evidenced by the provided output data.

The challenge made me think outside the box. First determining the first 3 month running avg and then determining the 6 month running avg by using the multi-row formula. Since we had to join back to the original record ID, I used the Record ID tool to give each row a unique record id to join back to the original records once the 3 and the 6 month running avg has been determined.

Able to complete. Not sure whether the early months needed to be average if full 3/6 months not completed with data. Completed by averaging all by 3/6, potential to use IF to amend if first fields didn't need to be averaged

Little complicated than the previous challenges. Learnt the power of the Multi-Row Formula tool. Attaching the solution for anyone to refer. The attached file has the solution in it.

closing my eyes and posting my solution before seeing how it fares against y'all.  outputs are correct, but rounded to 4 decimal places.

As some people already might have said, there is an mistake in the solution. Group by "HP Category" in "Multi-Row Formula (75)" was not selected:

Therefore the rolling 6 month average was calculated across different hp categories. As an example see the following screenshot.

The value in the top blue cell in the far right column should clearly be 128 as it is the first value. Instead it calculated (0+0+0+0+0+128)/6 = 21.333333.

Please find my solution attached.

Given the nulls involved, and how the instructions were written - it was difficult to check answer/validate workflow without utilizing the solution.
