I've been using the guide for about 3 months now and it has been a pretty good purchase for me. I know my overall fapturbo performance has improved because of this guide because I can think of numerous times when the risk management principles in the guide have saved me from big losses which in turn has helped me to be far more profitable.
One of the things I liked about the guide was rather than just saying "use these settings" it explains the reason different settings effect the risk and performance. And because different people have different tollerances for risk it actually has a number of different settings profiles with different levels of risk. It also explains why the risk goes up between the different settings.
The site has a lot of material and is reasonably well written too.
