problem is that theory doesn't hold true, a kid is going to press the button like crazy if not controlled and could inadvertently still hit the sequence.
I would rather see it in the original format and rely upon the lanyard as the safety device. Don't penalize smart people because of dumb people. If you know you are going to be relaxing swimming by the boat, pull the lanyard and you are safe from accidental kid presses.
