The convincing control cannot be explained in that amount of time. So what is the content? Ackerman shows his way of doing the convincing control as if you already know how to perform the convincing control.
The 2. way he is doing it, is more or less the way I already was doing it (probably learned from a script from Racherbaumer).
You cannot learn the convincing control from this download! If you research for different versions of the convincing control go for it: the price is low ;-)
The convincing control itself is imho in general and for most cases the BEST slide to control a selection to the bottom of the deck (without other action)!
However, if you want to learn the slide, search for other sources (e.g. "Versatile Card Magic" by Frank Simon). I saw there is a download from Racherbaumer "Cull-Mination" on this platform. I haven't read it, but probably it's a good start to learning the convincing control, too.
