Well, if it "works," are you sure you're using JH method?
It is so ambiguous and subjective that any "practitioner" of the "method" would be lying if they claimed they were using JH method. No one knows what JH method is! Sure, they think they know, but the evidence is in and is this: the "method" hasn't been explained clearly enough to permit an unbiased observer to replicate it. JH is like a brokerage salesman, looking for more commissions -- always in, never a loss. He will tell you about compounding, assuming that you don't have any losses, but will not tell you about the risk -- typical brokerage salesman.
