I can't imagine the first sale had as little in adds as it did, plus the sale after was for much less, so it can be excluded.

Additionally, the Slouch has no other sales, so that sale can be excluded.

300 to 330 would work as a conservative raise, as 460 looks a little high in comparison to the other sales.
