The "thrust" calculations seem to vary in accuracy.

It's not perfect because it does not use blade design. It only uses pitch and diameter but you can use the 'load' numbers to get an indication of whether you should expect more or less static rpm when switching from one prop to another.

Even after static running, the real test happens when you put the plane in the air because there's no other way to know if you like the way it works.
