Andy,
As you and Kelien know from experience, %Energy has pretty eluded my understanding
but this E/L graph that 46 frequently mentions is really easy to understand and use. I find it to be the most reliable thing in the new prgrams, along with the Bottom Line Betting screen. Admittedly, I am an amature in this new stuff, but every time I use the prgram (Val3) I get good results from those screens.
I understand it is some kind of a relationship between EP and third fraction - just not sure what.
At Binder's site, there is a very good thread discussing Energy with lots of examples. I find his site very helpfull.
