1:1 for HG Thousand yard stare

Vanquisher sales at 19, 20. Avg 19.5 -> 20

Sales for the Neckwear at 13, 14, 16, 20, & 23

13 & 14 excluded since it's far below buy orders

Keeping 16 due to Mindacos saying I should probably represent the majority, rather than just exclude sellers at 18-19

Taking 16-23
