Man I so wanted to be done with this thread...

Enhanced articulation: A number of procedures like joint-surface coating, re-lubrication, and tendon and ligament augmentation lead to more fuid muscle and joint action. Enhanced articulation provides you with a +1 dice pool modifer to your Escape Artist skill and a +1 increase to your Physical limit (cumulative with other limit modifers).
So basically the entire thrust of the arguement is that someone who has 4 cyberlimbs and has replaced every joint, ligament, and tendon in the body excepting their spine can get a +1 physical limit by doing the Spine but not by REPLACING EVERY OTHER JOINT, LIGAMENT, AND TENDON IN THEIR BODY. The logical fallacy inherent is to much to sustain within a universe that has magic, dragons, & cyberware.... mind boggling how this is considered fair.
