All sales at 78+ seem outlierish, based on all the sales in the ~60-70 range, the sellers in the 60-65 range, and due to all those sales not having B/O’s, and I can guarantee that all 3 sales would be much lower if we knew their B/O’s. Excluding 78+.

51 looks like a bit of a low outlier. Excluding 51.

Going with 59-67.
