| So, while there's not nearly enough data to be statically significant as was already mentioned, there exists the possiblity for a couple of trends developing.
The four earliest recorded serial numbers to this point are "good". This is the only time in our limited sample that we have a trend of four "good" numbers in a row.
While there is no direct correlation between serial numbers and dates purchased, if we assume that observation #1 is true, then the "bad" numbers start around the turn of the year.
The last two entries, the two highest serial numbers, are listed as "good". While this isn't nearly enough to draw any conclusions, we may have a starting line for "good" lenses.
A "bad" copy with a lower serial number than those mentioned in #4 was received on March 17th. Regardless of assumptions on #3, inventory has not turned over with shipments of "good" lenses as of this date.
