While the topic is still on the table, a tangent. Given: There are many methods of averaging intercepts and azimuths, fitting slope to plot, calculating slope and fitting to plot etc. Whether averaging in most circumstance is reasonable--or not--appears to still be open to debate ad infinitum (despite overwhelming evidence to the positive IMH0). I agree to disagree with the loyal opposition at this point. Done deal. To quote Yogi Berra, "In theory, there should be no difference between theory and practice, but in practice, there is." The tangent: The graphic methods are all straight line. I have read in texts (that also refer to averaging) references to "fairing the curve." This would make sense for a series of observations that are extended time-wise or definitely non-linear for other reasons. To my dismay there are no references I can locate (in the same texts) on how this is accomplished. Do any of the multi-cut supporters have input on how this is accomplished (in theory--or practice--on a yacht) will they please share? Thanks Bill
