This thread makes me think that the dyadic form of 6!:2 would be better if it produced the individual times and not the average of the times because then the mean and the standard deviation or some other measure of dispersion could be extracted directly from the results.
Also, perhaps a similar dyadic form could be added to 7!:2, but this is not as important for most operations. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
