Your math makes sense, and I understand your reasoning. I just wanted to point out that I have heard that you shouldn't go lower than the lowest pressure on the chart, regardless of weight carried. True? I have no idea, just relating what I've heard.;)
My understanding is that a tire can generate a lot more cornering force than the pressure to keep the tire seated on the rim at low pressures.
In other words, if you run low pressures, there is a risk that emergency maneuvers may cause the tire to come off the rim - and the lower the pressure, the greater the risk.
