Admittedly, the chart is old, I would guess 15 years or so, I can not state when the figures were actually printed. Since that time the fishery has changed drastically, as we all know, with many many anomalies to take into consideration, none of which should not be taken into consideration. Some of which are implied within your reply, which should also include what time of year it is and how well fed a fish is at that time and in-line with the availability of bait (as noted by Crabcakes). For instance, the same fish coming off the spawn in the early spring is quite a different fish in the fall after feeding all season.
When I used the chart it was quite accurate and is still a guide for reference.....not exactness, and not with-standing your log, I still believe its quite close as a guide even with considerations given to include "outliers". As I originally posted, ".....they were relatively accurate taking into consideration the "Min, Avg, Max"
You can see closely in the small print = "To help judge the weight of a striped bass in the field - for reference only". Even back then "they" are noting a disclaimer with an understanding there is exception. Even with your reference to the fish in your log hovering 40 inches still meet within the "min" range accordingly as you note.
With all due respect and not being adversarial at all I tend to disagree with your statement, in-part "....it takes a bit more time for striped bass to reach the poundage per length ratio that is seen on that chart." I disagree mainly because since conservation efforts have successfully alleviated the issue's of DDT's, PCB's and phosphates from land run off due to poor drainage and raw sewage dumped directly in water ways....bait populations have exploded. Fish are much better fed on a more consistent basis adding to their growth factor. And I would also say the fish I've caught (always with some exception) all still seem to hit or come close to the Avg. weight as printed.
As any book is re-released as a different edition.....so to I am sure the chart has been modified.....do you have an example of a similar and more resent chart to do a comparison to see what-if any changes were made ? I think that would really be helpful and informative to share with all. Thanks.
