Sales at 26, 27, 30, 34, 34, 35, 45, 49, 50, 50, 52, 53, 53, 54

4 buyers at ~35.5 on bptf:

Buyers up to ~30 keys on SCM

26-30 looks a bit low, will include 34 because a fair amount of lower sales happened and there are 2 at 34.

Seller at 45 hasn't been there long, including 50 but excluding 52-54 to balance out the range given we're excluding lower sales

Let's go with 34-50

https://backpack.tf/item/7090730793

looks like 37 keys:

May 4 9 PM: $114.12/2.4=47.55 ~48 keys

May 6 7 AM: $76.6/2.42=31.65 ~32 keys

May 9 12 AM: $138.74/2.45=56.62 ~57 keys

May 9 9 AM: $78.23/2.46=31.8 ~32 keys

The sales at 32 were definitely buy order dumps. However selelrs are now down to 48 keys (46 is unbumped) and buyers up to 37 keys. I think resuggesting at 37-48 will be a good idea tbh sionce the current suggested range is a little wide
