Ken It is a loose rule of thumb as I stated to support a safety argument I am trying to push. It was introduced on this site by others without criticism such as yours. You can't have been a participant on this site for very long or you would know this (even with 25 years of flying behind you)......search the archives.
In my view you should be criticising those (especially flying instructors, with a self proclaimed host of experience) who advocate flying some 50% over weight to newcomers who ask legitimate questions. I have no doubt at all that Stephen's calculations are correct and it is good that he has provided them....but they don't alter the above premise one iota and do not answer the original question about flying at 1300lbs. Here is another rule of thumb: For every 1/2 inch reduction in prop diameter you gain about 100 rpm static...not mathematically correct but close enough for general argument as mine was for aircraft of our dimensions. FLY A KR 50% OVER GROSS AT YOUR OWN RISK BUT DON"T CRITICISE ME IF I CHOOSE NOT TO AND ADVISE OTHERS LIKEWISE.
