tom, i think what swamp is saying (and I agree with him) is, where do you get 20mm from? how do you know that this is the threshold? is there actual evidence that shows that certain added stresses exist beyond 20mm?
the point is that a lot of people (including myself) will say that you are good with less than 10mm, or 15mm, or even 20mm, but that is not from actual experience or evidence, rather from common practice. 20mm could be a totally arbitrary number for all we know...it would be nice to have some real data, but i think there are simply too many variables.
