$17.00 / $1.8 = 9.44 keys

$24.99 / $1.78 = 14.04 keys <-- https://bot.tf/stats/listings/4PGOV854 B/O of 13 keys

Total sales @:

8.5, 9.44, 10, 10, 10, 11, 11.5, 13, 13 keys

Buyers up to ~9.5 keys, (just one tho)

Sellers down to 10 keys,

Gonna take the low end at 9.5,

and low end at 11 (13, 11.5, seems high given the unsold and lower sellers)

and trying to preserve range around unsolds.
