Short stroking a build by one tooth will knock off around 15 FPS. Unless you want the lower FPS, short stroking would not be worth the nano-second quicker trigger response. Ultimately, you are just shortening the distance the piston travels by approximately 2mm. As autsukisho and Splode said, the main use of short stroking is dropping a high-power build to field legal FPS and preventing premature engagement.
