LSS 3-Day Cycle Method ?

["Nick Channon" <nick.channon@xxxxxxxxxxxxx>]

Hi Group,
 
I wonder if anyone has a set of formulas for the 
LSS 3-Day Cycle Method, as written about by George Angell / Taylor ? If so, 
could you kindly post them? Also interested in your opinions of the 
method.
 
Many thanks,
Nick
