When video mode is ready it will stay down. I don't notice a timing difference on mine when it's down. I'll try it out tonight and really pay attention. Not sure if you knew but the skill shot also advances towards opening up the right ramp for coffin multiball.
Is your plunger always consistent on hitting the drop target? Bsd is known for having skill shot issues because of plunger issues. New spring, coil sleeve, plunger and mine is perfect. You can also remove the apron and adjust the coil/assembly to make sure it's hitting the center of the ball perfectly.
