1x (32.83*3)+20 = 118.49 ref, or 3.62 keys, or 3.6 keys
1x (32.83*3)+24 = 122.49 ref, or 3.74 keys, or 3.75 keys

(32.83*3)+19.88 = 118.37 ref, or 3.61 keys, or 3.6 keys
Using only bot.tf, we can find a range of 3.6-3.75 keys. However, take a look at the classifieds and note that the bulk of sellers are selling for 3.61 keys, rounded to 3.6 (https://gyazo.com/9c274d53354d8d802c3b7ea41d6b5ae0 + more). As a result, we can discern that anything above 3.6 can be ignored or treated as outliers. If more sales take place at a higher price, we can then, and only then, introduce a range. Until then, let's go with 3.6 keys flat.
