I did some coding a reproduced your Reulsts screen in the form of the pivot table.

Just double click on cell B1 of Sheets Results to refresh.

Condition is that the Data sheet starts on row 6 with first entry on row 7 or 8 as is now.
It was just fun to do.

The table will expand or reduce denpending on the number of month's and therefore also the text in the last column

8-months 6-months whatever applies.
It was just fun to do, and like I say, I like the 'brain gymnastics'

nice work - i notice on the original OP example he grouped the codes and sub-totalled - been playing to do that in a pivot and not so easy on the grouping
