I installed and tuned my NAP Quicktune 4000 fall away in less than two hours and went from grouping near the bullseye to 4 out of 5 arrows in the bull. It is a tack driver.

The cable was split so I called NAP that afternoon and they had revised the slide system. I remarked at how easy it was to set up and tune and the tech laughed out loud. Then he advised me that the only ones that have trouble setting them up and tuning them were the Pro's.

I added 2 fps in the switch over but the accuracy is phenominal and I'll never go back.

On a note of the physics of the arrow, once the arrow leaves the string it is on its own and anything touching the arrow will significantly add to the drag coefficent on the arrow. A fall away looses contact on leaving the string hence no added drag which results in a much more accurate arrow flight. The difference in drag coefficient is obvious in the 2 fps difference between a standard prong rest (I used the Quicktunew 1000) and my QT 4000. I have not done th math but I assume that this would also result in an overall increase in KE (though very small).
