I have done the same last year with moment....
and I am sure many others did! (to save execution
time, I added a keyword maxmoment, such that it
does not compute the kurtosis if I only need the average).

It's incredible how much time is wasted because
ITT will not implement such an obvious improvement
in an existing routine!

Ciao,
Paolo
