Dave,
There are externalities involved which may naturally skew the scores.
Remember that correlation does not imply causation. One thing from which we
benefit from in the Southwest, and to a certain extent in South Central is
wonderful weather. Flexible stuff dries out, but everything else hardly
deteriorates. There’s also the possibility that there are a number of
excellent cars in an area. California has long been a Mecca for automobile
lovers. Standards of restoration may be slightly higher there. I remember
the first car to receive a perfect score at the JCCA concours was a Mark 2
from CA. Not only was the car a trailer queen, but the wheels barely touched
terra firma. The owner had made tire booties. He drove the car to the
concours spot, pulled the booties off the tires and rolled the Jag the last
foot off the booties. We viewed the procedure with a mixture of mirth and
admiration. I know another California entrant with a more modern four-door
Jag who has two sets of wheels, tires, and front seats. He puts the perfect
set in for concours. I had one club tell me that they judged more cars than
indicated on the JCNA site, but that they didn’t register the scores for
their club members who were only showing at their concours. They were in the
SC region.
While a strict statistical analysis may be indicative, you have to take into
account all these external factors. IMO, the only way to do that is to
follow car from concours to concours and compare their scores. Then you
would have to factor in any improvements made by the entrant. Usually what
happens among the true competitors is that when a non-authentic item is
found, they fix it before the next show. So it’s really a moving target.
Probably, the most accurate analysis would involve reviewing the scoresheets
from concours to concours and comparing deductions, especially
non-authenticity ones. If you discovered a pattern where a club or clubs
cars handed out a higher percentage of perfect scores, then at a subsequent
concours, they received one or more authenticity deductions, that would be a
much stronger indication that the judges at the earlier concours were not as
familiar, not as well trained or not as sharp eyed as the later judges.
That said, I don’t disagree that judging disparities exist in JCNA. To that
end, I don’t think it would be a bad idea for JCNA to receive a copy of
scoresheets from the local clubs, for review. If they found a pattern where
a club was giving consistently higher scores than a subsequent club, it
might be ground for a review of their judge training and testing.

Subject: [concours] A Review of JCNA Concours Scoring for 2011
I have enjoyed participating in JCNA Concours events for more than ten
years. However, in recent years I have begun to question whether all Jaguars
participating in Concours events across the six regions are held to the same
strict JCNA judging standards. Other Concours participants with whom I have
spoken have voiced the same question. In order to satisfy my own curiosity,
I decided to take a closer look at Concours event scoring. This lead me to
conduct a detailed review of Concours event scoring for the entire JCNA 2011
Concours season.
The purpose of this review was to determine the percentage of perfect scores
awarded at each Concours event during the
2011 Concours season, both by Club and by Region. First, the number of cars
judged was established for each event.
Second, the number of perfect scores was tallied in the Champion, Driven,
and Special Classes. Third, the percentage of perfect scores awarded was
determined based on the number of cars judged. In addition, a percentage
comparison was made of the perfect scores awarded in each of the six regions
participating in 2011 JCNA Concours events. Finally, the number of perfect
scores per event for each region was calculated. Statistical data is
available upon request.
As a result of this review, the following information was
ascertained:
.1,380 cars were judged across the six regions of the JCNA during the 2011
Concours season.
.136 perfect scores were awarded in the Champion, Driven,
and Special Classes.
.10% of the cars judged received perfect scores. Using this percentage as a
benchmark, a comparison was made between the perfect scores awarded in each
region and the percentage of perfect scores awarded for the year across the
six JCNA
regions, the aforementioned benchmark percentage.
.The highest percentage of perfect
scores awarded was in the South Central Region with 19%. Second was the
Southwest Region with 12%. Third was the North Central Region with 9%. There
was a tie for fourth between the South East and North East Regions with 8%.
Fifth, and the lowest percentage of perfect scores awarded, was in the North
West Region with 3%.
.The highest number of perfect scores awarded per event was also in the
South Central Region with 5.1. There was a tie for second between the South
West and North Central Regions with 2.9. Third was the North East Region
with 2.3. Fourth was the South East Region with 2.1, and last was the North
West Region with 1.0.
The above information raises several interesting questions.(To be
continued.)
