What he said. Plus, if you empty the accumulator before the pump starts, water delivery fluctuates.

But it already does if the air pocket is maintained at the top.
The air pocket (at least on my RV water heater) is pretty small, and doesn't provide for a whole lot of accumulation. If, however, you use the entire tank for an accumulator--which of course precludes having hot water--it can indeed be quite effective and of a sizable capacity. I found that out, and in the process made myself rather befuddled before I figured it out, by wrongly resetting my bypass valves a year or so ago.

More water will flow in/out of the accumulator at a lower bladder pressure. The idea is to compress the bladder air as the accumulator fills. Compressing the bladder air will increase its pressure. The higher the bladder pressure when empty the less effective the accumulator is. You essentially turn a 2gal accumulator into a 1gal accumulator with higher bladder pressure.

I think that you mean 2 lb below cut-on/turn on, pressure, set at 2 lb above the pump will never turn on.

No, I meant what I said. For example, if the pump cuts on when the pressure is 18 psi and cuts off at 55 psi, I would set my tank at 20 psi. As soon as the tank empties itself, it no longer exerts any effect at all on the water lines and the pressure will continue to drop, all the way to zero if the pump is turned off. Note that these are example numbers and not to be used to set anyone's tank.
A bladder tank should be set 2 psi below the pump cut in pressure.
