Again, from what SJ says, it sounds like it is possible to get around most of the issues I anticipated with unlimited-engine QNP, if you use different sorts of values from the ones I used in Proportions.
That is what I was hinting at.
Also, I never said that either system was intrinsically better, just that I prefer unlimtied QNP. I think that all resulted from a word being taken differently than it was intended (proper-QNP).
