Some key points to bring out at this point are:
- Tape measurements have so many built-in errors that they are not considered credible.
- Chiropractors have a totally different reference point (non weight bearing) and 95% of the time feel that the opposite side is short. So, if you use standing based measurements/xrays and feel that the right is short, chiropractors will feel that the left is short. There reference point is not the ground.
