Anyone ever heard of the "Cashflow Cruncher"?

[Dan Turkel]

Hey everyone, I recently came across a spreadsheet called the Cashflow Cruncher. It seems to be a part of a larger company called VIP Financial Education. They speak about using "Debt Weapons" to cut down on the amount of time it takes to pay off your mortgage. I'm trying to figure out if their techniques are legit or not which is why I'm making this post.

Here is a video (which starts 45 min in) explaining how they use the "Cashflow Cruncher" to cut down on the time needed to pay off loans: https://www.youtube.com/watch?v=OvSrBXm7fOY#t=45m0...

What are your thoughts on this technique?
