Well, Greg, I will look forward to seeing you (and your car) In New Bern. Do you have your hotel reservation yet? And I want to say that 1966 is one of my favorite years, so I may be hanging around your car a lot!
The 5-point rule applies only to AACA Grand Nationals, whereas the 10-point rule applies to regular AACA meets. In order to place for an award (First, Second, Third), the car must score above a set minimum number of points AND be within the "points spread" of the highest scoring car. Reading the AACA rules, a car must score at least 380 points to be a First, but ALSO must be within 5 points of the # 1 car. If all cars score 380, then all are Firsts. If your car scores 380, and the top one is 385, you both are Firsts. If your car scores 390, but the top car scores 397, he gets the First, you get a Second. I don't like it, for a number of reasons that I've stated on the AACA website, but the rules are set and imovabale, apparently. It took me 4 tries to earn a Senior, due to this, mainly, I feel, because I drive my car, and other cars in the class only see the light of day between the trailer and the show field. This is especially true with the cars entered in AGNMs.
That's why I am reconciled to not being able to compete for a First. But I think I can score 360 or more, so a Grand National Third would be good, and I look at it as "preferred Parking" within the show field.
The First at Cherry Hill was a true surprise, but since CLC judging includes operation of systems, rather than stricly cosmetics (as AACA), BATILAC did well. Like you, I am a stickler for detail, and I can't stand to have a system that is not operational. The Cherry Hill judges checked to make sure that my Wonderbar scanned properly, and my washers squirted, but none of that will count at New Bern.
But forgive my rant...
I am sincerely looking forward to seeing some magnificent cars in May.
