5 month old price, low end needs to come way up

All non pure offers have their mid price on bp.tf multiplied by .9 to account for overpay. USD offers count buds at $37 USD

Best offers - GE Ushanka + IASTE Mirror + 2 pure or $85 USD(4.1 + 4.4 = 8.5 * 0.9 = 7.65 + 2/(2.3) = 9.7 / 10 pure), $320 USD = 8.6 pure, 8 pure, GE Ushanka + $230 = 10 pure

Best offer - same 9 pure offer

Best offer - Burning Modest for Burning and Hearts Beak (21.3 - 9.8 = 11.5 * 0.9 = 10.4 pure) Modest is duped though

In conclusion there are sadly no current sales to go off of, if you can find one, please let me know. Highest offer is 10.4 pure after accounting for overpay, but the modest is duped. Offers 8 are extremely common (more than one per trade in general) and 9+ offers also show up occasionally. Only 2 trades had B/Os and both were set to 11, so we aren't setting the highend above a B/O. Just deciding to keep the current high end and just bump up the low end. Talked to Woifi about bumping the higher end, he didn't think there was enough proof Please show me some counterproof / additional proof so I can make this as accurate as possible.
