It's like this:

Reverse/Brake-------------------(((Neutral Zone)))-------------------Forward

When you adjust the setting it adds or removes the (( )) from either side of the neutral zone on the Tx channel. The Tx will not broadcast a signal when it is inside that zone. Basically it relates to how "touchy" the throttle is. If you make the zone too large, say for example the stock 12%, the throttle will turn on at 12% or the brakes will engage at 12% to start. There will be no resolution lower than that because those values are in the Neutral Zone. I find 6% works well.

I hope I explained this correctly. It was harder than I thought!
