Ok, yet another thing I was told and learned wrong. 
EDIT:
Define Pre-Load: Pre-Load is how much the springs have been pre-loaded with zero pre-load being the point at which the springs, slider, spring plate, and coil nut adjsuters are touching with no play. The amount of threads showing above the coil nut adjuster is NOT that same as pre-load.
^^^ for anyone else learning Coil Over speak like me.
