You were not "docked". There is a proviso to give an "extra" 5 points for complete set of decals. I pointed out to you that you were missing the decal in question just to let you know no penalty, just no bonus. (If you want to see the AROC judging/scoring sheets, you can download them from the AROC website.)
At least that is my recollection, it was hot and we were sure busy judging all the 70 to 94 Spiders.
