Specialized Averaging Needed

[Dzp1_47]

Hello,

I'm trying to average scores, but need to ignore/drop the lowest score for every six entries. But the catch is I have to ignore the lowest of each six groups of scores. So every six data entries triggers the ignoring/dropping of the lowest within that set and so on and so.

So after 18 entries, the average is reflected as the average of 15 scores, with the lowest of entry 1-6 dropped, 7-12 dropped and 13-18 dropped. Also, if the last data group doesn't have 6 entries yet, no low is dropped. I'm having a hard time doing this without a massive nested if statement. Hoping there is a better way! Can absolutely do this in multiple steps if it makes it easier.

Thanks for the help!
