Precision and linearity

OK, ok..I wasn't going to expend bandwidth getting into this one..but I 
think Nigel's wrong when it comes to 'convincing peers'.  It's a simple 
mathematical proof that the line between two points is straight (assuming 
Euclidean geometric system)... in fact, the addition of any more points 
just allows would-be quibblers ammunition with which to dispute your 
choice of line.  Now, if only I can convince my committee members of the 
validity of that argument  ;-)
