I must applaud the quality and integrity of this project. The info is very well put together and Alan has excellent communication skills for delivering it in an entertaining format. Its unusual for someone of his caliber to personally take the time to provide a forum like this to offer his expertise in such a manner. I can tell you that his time and insights are well worth the price, even for a professional as we are always weighing options and methods and remain (hopefully) open to alternative ways of finetuning and using the tools at our disposal. Well done!!
