Calling 67 an outlier.

Total is (46 + 36 + 0.56) = 82.56 keys

----------------------------------------------------------------------------------------------------------------------------------------------------------------

New Sales are:

70, 78.32, 82.56

Sale @ 70 can be ignored as Dapper it was sold for has no reliable sales.

Foamy's Part:

Your appraisal of the mp sales is not correct. i'm not sure what went wrong there.

190$ = ~96 keys

180$ = ~91 keys

Both of these are done at the current key rate of 1.98$. this varies slightly over time, so they could both be a key or two off, but not more than that.

That rotation sale really shouldn't be used here; especially with the wonky mini with a wide range where the high end was rejected as outlier, it is more of an indication that the rotation needs a wider range.

All in all this ends up being low, though I guess a drop is undeniable. With the abundance of lower sales, a range of 80-115 (rounding 78 up and 117 down) would work here.

Setting new range from 80 - 115 keys.
