Marty's part:

https://imgur.com/a/yDwcZeH - MP seller for ~91 for the past 2 months, should be included

Also, any reason you omitted 37 from the Black Watch mini? Nothing really counters its inclusion, if those two sales are all you have. Would put that sale basically equal to the seller mentioned above.

Total sales @ 91, 96, with Marty's seller at 91.

Taking 91 - 96 keys
