Gladiator.tf is messy atm but around the time of the sale a key suggestion at ~64 ref was made https://backpack.tf/suggestion/65e335009bae19299708fdfc

This makes the sale 4.02 which rounds to 4 anyway

Jan 25: $8.99/1.7=5.29 ~5.3 keys

key price https://marketplace.tf/items/tf2/5021;6

(1.7*6+1.72)/7=~1.7 (using an average since there's a little spike)

Sales at 4 and 5.3 (rounding to nearest 0.05 since the median is below 5 (4.65))

Going with 4-5.3, although 4 sold within a day nothing proves that it's an outlier compared to the only single sale at 5.3
