Question for you street guys running low 14’s

From the “How To Hook And Launch” book: View attachment 1715750518 Not the be all end all book but I rely on it for what I do and has served me well at my level of track experience. All my times are damn close to almost spot on (except for mph, due to aero)
I remember running 13.8 @104 with no hook and spin. The car should have gone 12.5 or so. 60fts were crap.
