The CAA answer is that by changing the rosters to avoid what might only be a 1 minute overrun will cause roster disruption. As BT says if you do a 60 hr 7 day week the next is going to be a lot lot less and this is the protection that CAP gives you (hence why unchallenged by a Union).
CAP also now requires a meal opportunity, you've never had it so good (joke)
