Woifi's Part:

Mini lucky: https://backpack.tf/profiles/76561198141386941#!/compare/1536105600/1536192000

sale for 14.5 keys, sellers on the lucky for 13.5 keys, so 14 keys average, would make that sale 25 keys, smoking phantom sale is 19 keys I guess since it could be rounded to that.

29 keys is definitely an outlier here, smoking ywnm too.

Seems like this should be resuggested at 19-25 keys.

Taking 19 - 25 keys.
