Can't have a price range based off on one sale alone.

You will need a mini for peak. Also, check Marketplace if there are any recent sales for the Lil' Bitey, that can help with your suggestion as well.

Added ~<1 sweets for 36 pure

https://backpack.tf/profiles/76561198088730620#!/compare/1593043200/1593129600 - buddy was sold for 31 here, 31 + 5 - 1 = 35

https://backpack.tf/suggestion/5f1bb40afae498368d512826 - Peak mini @ 49 here

49 + 6 + <2.5 = 57

That gives sales at:

35

41

57

Piotrex owned the hat for over a year (https://backpack.tf/item/7243363264) before selling for 41, so I think your sale of 57 is probably high. Given the lack of bot.tf and the fact that 35 sold in 2 days (judging by the history) I think calling 35 low (likely qs) is probably ok, making this 41 flat with an outlier on each end

41 flat seems like the best option here.
