OK, I see where you got your understanding now.
On the graph, the left axis is for the number of auctions, the right axis
is for the selling price. You read matched the wrong scale to the data
points.
Maybe I should put a label on the axis?

John,
You need to look again.
Here are the analyses for all the 50/55's non-Macro.
FLength #Auct Low High Avg StdDev
50/1.2 6 184 266 236 28
50/1.4 105 20 168 62 20
50/1.8 154 10 99 29 13
55/1.2 16 32 305 181 84
I did discover an outlier on the 50/1.8 data. A 50/1.2 for $255 was
listed as a 50/1.8. The above data represents the correct analysis. But
that only changed the 50/1.8 average from $31 to $29.50.
There may be actual errors in the data. Thanks for keeping me on my
toes.

The prices don't look right at all. For example, you show a typical range
for a 50 1.8 of $60-95. Not in the ballpark. Something's wrong.
