"How do you know that the marketplace sales had these B/Os if the item histories are untraceable? It's almost impossible to identify the sellers that way. The Mannco sale B/O you posted doesn't match either."

"Regarding the Mannco sale, there was a huge fluctuation of key prices on July 7th ($1.76 instead of the usual ~$1.9). The key value taken there should be $1.94, the reasoning is explained here:

So the Mannco sale will round down to 6.5. 6.5-9 should be okay here I guess."
