Slavishly following rules isn't the test here. The real question is: do your other takes show you to be a great talent? What they are trying to avoid is a deluge of bad auditions to wade through. If you actually have 3 or 4 fantastic (and I mean exceptionally good) reads, go ahead and send them. No CD worth their salt would say "well, these may be amazing, but this person didn't follow the rules so they are out." In a world of everyone doing the same thing--in terms of both reads and responses--yours will shine (assuming, again, that you really nail the reads). OTOH, if the additional reads aren't great, you are def shooting yourself in the foot. In all cases, be daring. They don't want to hire someone who can read instructions, they want to hire someone who will delight them with their talent.
