A couple of years ago I messed around with Taylor's LSS method, but it didn't get me very far. There are some mistakes in his book (typographical errors probably) so that didn't help either.
I also know someone who thought that George Angell's book was a pile of you-know-what!
However, it did start me off on the road of looking at cycles - and those were good! In my mind the 3 day cycle is just too small to be of any use.
