Okay so the sales here are yours at ~81, the non-ks on the SCM for ~95, the prof ks on SCM for ~100. Current SCM listings are much lower than those two sales and are more in line with ~80.
All marketplace sales are outdated, but the most recent ones also back up a value roughly around ~80 (a little higher due to other key conversion rates)
For future reference, it helps to have an overview at the end in which you list all your sales, or highlight all sales you have in bold, because its difficult to assess which data is used, and which of the data are sales or sellers. The summary at the end will also make it easier to show where your range comes from; in this case, this couldve been 81 (or 82 as 81.5 rounds up if its actually .5 or higher), but this is close enough for the purpose of this particular suggestion.
Since I botched it so bad last time, here's another go.
