Sellers at 7 and 8 clearly suggest MP sales at 9 are too high. Page of buyers at 7 keys suggest 6 is a bit low here. Although unconfirmed, the sheer number of recorded gladiator sales at ~7 keys (3+ datapoints) is probably enough evidence to call it usable here. Buyers support taking 7, and multitude of 8 sellers and seller down to 7 don't support including any higher values. The STN listing selling would also support this value.

Taking 7 flat.
