Armando started a very interesting discussion on Facebook recently. He asked what is the result of the math ratio HIE*1000/(PP-TP), what is interesting you get a very similar numerical range if you invert the equation and remove the visibility constant (1000) ie (PP-TP)/HIE.
It seems that most people fall into a very small range between 28 and 32 or for the inversion the range goes between 31 and 36. I am, for lack of a better term, calling this XMR or the Xert Magic Ratio which seems to indicate that your signature is within the reasonable range.
It is an interesting discussion and for those who do not follow the FB thread I thought I would post it over here to further the discussion and thoughts on what this really means?
