Wonder if this figure is including other operators, in much the same sense the shuttles for Leeds Festival are all technically operating "on hire" to First West Yorkshire?

I only saw parts, mostly on Friday, from what I can remember from the event, there was the B9TL, ALX400 and the Olympian as stuff which is City owned/liveried, then there was hires such as the artic Solar Fusion: http://flic.kr/p/2sqtoAD  a Mercedes Citaro demonstrator which had come up from A&A plus at least 2 other buses from A&A - so that's 7 from what I gathered, perhaps there was more but I don't know, doesn't help with looking stuff up that people easily confuse A&A Coach Travel and DM Motor Services' fleets with one another.
