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.
