Rounding to the nearest 0.5 for neatness

We have 13.5, 19, 20.5, 21, 21, 22

Seller at $40 is 19.8 keys taking the median key price of today but can't rely on that because keys on there have been inflated recently, also giving the fact there are two sales at 21

Seller at $55.32 (26.34 keys) and buyers at $32.25 (15.35 keys) on SCM

In this case, 13.5 is clearly a low outlier given the fact buyers are higher.

Going 19-22
