Rob, you will never convince me that you set out or bought a machine for the sole purposes of looking for glitches and just happened to masterfully uncover this one.

As far as we know, so far, the person who discovered this glitch originally was a strange degenerate gambler who most likely had all kinds of crazy theories about machines, and because of this, along with his desperation to chase losses and gamble every last penny on a machine created a situation where he would constantly switch around denominations and games while constantly feeding bills and cashing out so frequently that he just happened to discover this bug.

If in fact you discovered this glitch on your own, I believe it would make sense that you discovered it while using your crazy betting system. Your system just so happens to also require switching around denominations and possibly games. And if I recall correctly, you also cash out many times during a session or whatever you want to call it.
