I also make it clear from day one who the instructor is and at any time if that is forgotten I reserve the right to end the instruction.
^^^ That. I like the way you teach

No. Not during a class. If you think the instructor doesnt know what s/he is doing, get a different instructor or do some additional teaching to your child later. Otherwise, let him or her teach and dont stick your nose in correcting them on this and that.
Oh please. You are stretching just to try to make a point. Reading a few books on diving gives you the knowledge and ability to disagree and correct the instructor? Yeesh.
If I am teaching a course, I am responsible for the student's safety - I take it very seriously and I wouldnt be too thrilled if someone with a handful of dives decides he knows more than me b/c he's read a few books. In my experience, the "certified diver" family member is far more likely to be wrong than the instructor.
Now this is where you bring in the strawman argument of a completely incompetent instructor who would have been a safety hazard were it not for your intervention.
As I said - if you want to add to the content, do so outside the course. Dont interrupt and disrupt the class. You (I mean this generally, not specifically you) are FAR more likely to be mistaken than the instructor, assuming that s/he is competent.
I've seen it before. For example, when I teach, I have a progression in how I provide information - sometimes, I provide only the basic facts and flesh it out later. I have certain points where I let students make mistakes first and try to self-correct before I step in. I have had well-meaning friends and family jump the gun, and start providing too much information, overloading the student - or confusing them with conflicting information, etc. This throws off my teaching progression and makes it worse for the students.
If you think the instructor is not teaching properly, get a new instructor. Otherwise, let them teach and fill in whatever you think is relevant later.

I like the way you express your teaching method. The fact remains, however, that not all instructors, even competent ones are going to be 100% perfect and correct in what they say. They will also teach in a way that some people just don't get it. Expressing that in class is the only way the student is going to make it clear they need further help. This attitude of "instructor knows best" is simply ego talking. You are clearly a diligent instructor who plans carefully but the best planning doesn't prepare you for every student. Some simply will need a different set of skills (of you) to be taught. Maybe that is a different subject than what you're discussing, but it's part of what I mean.
Blind faith in ANYONE for any reason is foolish, especially in a situation like SCUBA where it's potentially life-threatening. No instructor should be just allowed to push through on a subject until all students either understand it correctly or have arranged for further side instruction in private. If that means interrupting the instructor's plan, then so be it.
