Total Sales

120.5 & 85

2 sellers at 85 | buyers at ~68

https://imgur.com/a/OF1QmbQ

excluding 120.5 cause all sell orders are lower at the moment so just taking 85 flat

uhhh so there are 2 new sales on market place on June 1st and June 2nd (today is June 4th) of 189.99 each, (189.99/1.67=113.8 keys)

https://marketplace.tf/items/tf2/31385;5;u299

However, there are still sell orders for 85, 100, and another 100. I'm still going to not include the marketplace sales because of the MULTIPLE sell orders below, but just thought that I need to at least mention it here.

Though if the multiple super recent sales are supposed to "weigh" more than this, I can change the suggestion. Though based off of what I see other people tend to exclude because of sell orders, I think I should just leave them out.
