If the user is good enough to pass your tech course, all well and good, he can get the codes and program to reset the service timer for his unit. That should not prevent the unit obliging him to service it though: it is not that hard for the unit to check that all the cells are replaced, so people do not just use the "reset" program, and the "reset" program should require him to enter valid serial numbers for the O ring kit etc.

Alex, when you say "should require" are you voicing your preference? In other words, are you saying "If I were to design a system I would ....".
Or are you saying that governmental bodies in a position to mandate should require that no other type of system be sold?
For me the difference is important. I wholly support your effort to come up with a new system, a new manner of managing safety, another alternative available to divers. To that I say "Go Alex!" Great, another alternative.
Where I would not be a supporter would be any effort by you or others to solicit governments to support your point of view with the aim of saying no other model is lawful. So, for example, saying the expert user model is not lawful.
Just wondering what you are actually advocating?
