You're probably in the 0.00001% of Buick/SyTy owners then... Because 99.9999% of everyone I know doesn't give a rat's ass about cutting a good light (which is now .000 so you know).
I agree that people not knowing how to stage, pulling past the beams, taking a long time chaps my ass too, don't get me wrong. But my guess is that the majority of the people posting to this board aren't serious enough to go out and buy a liberty 5-speed in order to courtesy stage on a 4/10s tree and leave with the desired amount of boost.
Furthermore, most of the people here don't have transbrakes, so you've got most people trying to stage, put the truck in netural, pull ebrake, pump brakes, give gas, put back in drive, build boost, etc... Most people absolutely cannot do that in the time between staging and the green light. And almost nobody here will sacrifice a good launch for R/T...
