FishCrimes' Part:

-Sale 1 might actually be untraceable. If it were SCM, it would have entered the buyer's inventory untradable unless it was scanned late (which it very well may have been, date set at 8/20).

-Sale 3 is calculated wrong. The former revolver owner added about 4 keys in stuff, meaning this sale comes out to ~21.

-In sale 5, you can trace the kwatt pile because it sold for the kwatt pile (22 keys).

All thing considered, with the revolver sale fixed, it's more than safe to call 16 low now. 17-22 is the call. Staff and I agreed that while the whoopee is duped and 30 keys, the difference would be negligible and the sale would still be high.
