You have neither with certainty under any system.
DrMike is closest when he proposes a system with 4000 cells of varying characteristics . . .
even then the best we can say is that the odds are much better.

But I can't afford 4000 cells...
and besides very little in life is truly certain if anyone is going to follow that line. 3 gives a good idea. I'd not be comfortable with 2. A third plugged into a coputre to calculate deco - great. I'm still not convinced this is the best way to go. the deco regulating sensor could be the one to go in which case it's back to assumed set point deco. Voting logic across three when it's reliable.
Of which anyone got experience of the Diamond voting box and HUD set up?
There is a degree of necessary care and then there is practicality in the available prep & kit up time and potential for missed and bailed dives owing to uncertainties. I like being in the water, and I like spending necessary time in the shed and pre dive, but prefer to keep it to the necessary, there's pints to be had!
