Wheel studs

I was looking on NHRA's site for wheel stud info. I'm a bit confused, if I understand this. 13.99 and slower doesn't require longer studs, unless your running slicks? does that mean a DOT type as well? Can you run stock wheel studs and slicks or DOT type slicks if you run slower than 13.99, or do you have to use the longer studs because you are using a sticky tire with a slow et. May I'm reading into this to much. Running a stock 360 with 3.91 gears.
