There are alot easier ways to improve your shot count. Make sure you are underboreing your paint. This is HUGE in getting better shots per fill. Also make sure the marker isnt over lubed the orings should be wet looking not gummed with lube Also dont put any lube on you bolt or the can it slides on this causes drag and actualy reduces performance. The dwell is one of the last things to mess with on these markers. Also it can depend on how consistant you out put pressure on your tank is. So in short dont mess with the dwell unless these things have been done or looked at.
