September 7 3 AM: $28.29/2.30=12.3 keys

October 16 8 AM: $14.81/2.35=6.3 keys

Buyers are at 7.44-8.21 keys so excluding 6.3, 6.38 and 7. Sellers at 15 keys with none sold at that price

This leaves us with 9.04-12.3, median value is 10.67 so gonna round to the nearest 0.1 keys. The range is now 9-12.3

Gonna go 9-12.3 keys

(hopefully I didn't mess it up, this is the most effort I've ever put into a suggestion)
