You will do even better (electricity use & pump/tank life) if you drop your pressures even more. I mentioned in the other thread that ours is at 20/35 (or so). It seems to serve us OK. It won't blast you out of the shower, but it's certainly enough to wash the shampoo out. Overall savings likely depends how hard a time your pump has reaching that highest pressure though - our 3/4 hp convertible pump running shallow well mode in a what is likely actually a deep well situation struggles when it gets up over 35. But the one (main?) side effect is that at lower pressures, less water will be wasted in those 'tap left running' moments - which reduces your overall pumping even more. Adding more tank capacity will also reduce your pump cycles & give more reserve for power outage situations - adding another tank is on my to-do list here, somewhere...
