Regarding Bk and Troopers....
Blue Knights have a very easy show this year, both musically and visually. To me, this explains the slow rise in score for them. They've peaked. Score will continue to rise, but probably not very steeply.
Troopers have a harder show than BK, but Troop is still being outperformed by their own show. As skill with the show is gained and improvements to the show are made we should continue to see Troopers climb faster than BK. Just a few weeks ago BK was nearly 9 points ahead of Troop. 5 points of BK's 9 point lead have been chipped away. I'd say that is pretty compelling.
In short: Troopers show has more room for improvement than BK...and while I'm not saying Troop will pass BK, I won't be completely shocked if it happens.
I hope it happens.
