Buyers

http://www.tf2outpost.com/trade/28185785 - 8.33 Refined - Inventory has been empty for almost 2 months and has never had a Siberian Facehugger in their inventory.

I believe it's fair to discount this buyer.

This buyer seems to contradict both the price I'm suggesting and multiple sellers for 8.33 Refined and below.

I believe this proves 8 Refined is not a quicksell/buy price which is why I am suggesting 8.11 Refined even though the seller at 8.11 Refined is considered young.

I am excluding all sellers/buyers with their price as "bp.tf price" as the item has a flexible price making it an unclear price.

I am willing to re-suggest another price by popular request but I see no problem with this suggestion considering the information and proof I've provided.
