I cant find those specs in sale 1 anywhere, and that is 99% cerain wrong anyway (most of the items return to the seller, hes probably brokering or something. His sale is the ywn sale).

That leaves you with 3 sales, and the only one you're using is probably one you should not be using. The ywn is two years outdated; id be hesistant to cap that at that BO, even if there was nothing else on it. however, the otehr sales show quite clearly that 80 is probably too high: a neutron star full metal drill hat is never going to be anywhere near 80, and youre calling the c9 modest an outlier here without any rationale, whilst thats your closest to reasonable sale you have here.
