I think that obtaining ideal voltage per cell to begin and for most efficient production has to be a product of more variables than the number of cells and input voltage. Other factors such as the resistance of the plates and of the electrolyte must come into play too. Your figures certainly point in this direction.
It must also be the case that the voltage per cell will change with rising amp load, due to the V=I over R rule.
These hypothesis may also explain each cells "sweet spot" and may even allow us to develop a formula to calculate it.
