CLASSIFIEDS:

Buyers are up to 43.58 keys. Excluding 37 and 43.

SUMMARY:

1 @ 37 keys

1 @ 43 keys

2 @ 45 keys

1 @ 50 keys

CONCLUSION:

37 and 43 are under buyers, excluding both.

While 45 seems low as well, it seems common here, and there are 2 more sales at lower. Going to include 45, even if low, due to being common. Lower sales support.

Taking 45-50 keys here.
