The quick-shifter is designed to work in one swift shifting motion, DO NOT pre-load the lever before shifting, DO NOT touch the shift lever until you're ready to shift. In one swift motion, just move your foot through the entire range of the shifter's travel and you'll find that it cuts the ignition just enough to allow the shift to happen smoothly with full contact of the gears. The DQS system is dynamic based upon the RPM, gear and throttle position, so it will make a longer cut when you're at lower rpms at partial throttle than it does at higher rpms at full throttle. If it's not working smoothly for you, check your technique against want I posted. Once you get used to it, you'll never want a bike without a quick-shifter again, I promise!
P.S. - Clutch levers are SOOOO yesterday!
