John:
I am familiar with Richardson's method. I just haven't used or tested it
and, thus, have no real input to any discussion about it. I try not to
offer a professional opinion on a technical subject if I don't have
significant data to back up what I'm saying. If you want my personal, gut
feeling, unsupported by any technical data, I can supply it but don't know
what value such an opinion carries.

Maybe Peter does not know about Richardson's method Tom - it might be worth
explaining briefly as it is a unique concept.
