As to the question of "is it worth it to purchase?" My answer is no, do not purchase. Only as good as all the other systems out there. Eventually fails, and way to complex to use. With it being so complex, often you will not have time in between hands to figure what you want to bet and to get it down on the table. I know of two others who bought the system, and found the same problem, and after it started to fail for them they shelved it also. Dr. Tom is a good guy but the system is too complex and does fail.
I have moved on to my own system which is fluid and I am at a daily average of $87.56 since January 1 2017. Am at $18,390 for the year.

I bought this system for $750, and it is quite complex. It worked for awhile, then like all systems started to fail. I also saw some of Dr. Toms actual shoes and when he gets to a point of failure he does not follow his own rules for bet placement, and those shoes show a win. I wondered if he posted errors, asked him, and got no reply. So, does he show only shoes that win, or does he 'past post'? I don't know, but him not replying made me wonder.
