There isn't really a pure "execution" score anymore. The subcaptions are supposed to reflect design and performance, but it's not a categorical distinction. If you don't have the demand, you cannot get a perfect score in performance even if it's technically flawless.
I shouldn't have used the word execution.....my fault. I'm referring to performance as opposed to ensemble and technique as opposed to content. While I agree with your basic premise I would argue that going with your theory the Troopers visual demand is not of greater "quality" than the Colts and does not constitute a .70 spread in performance better than the Colts in this caption. If their demand was that much greater to effect the performance caption it would have showed up in the ensemble caption as well. The difference in ensemble was .10 last night with the Colts having won that caption by .20 the night before. So therefore (based on my opinion and according to William Chumley) there must be quite a bit more for the Colts to clean.
