70% Rule

In my hips and shoulder blades one side of my body has a much greater range of motion than the other. When applying the 70% rule to movements on my weaker limb/side should I also reduce the range of movement on my stronger side to 70% of the weaker side in order to maintain balance in my postures and focus on developing the weaker side, or should I practise over a different range of movement on each side?
The former makes more sense to me, especially when applied to joints in the legs, as this will maintain an even height and balance, any comments?

Just as an after thought, my process of ‘discovery’ might be useful to someone.

I noticed the difference in range in my shoulder blades when extending both arms simutaneously to the front (an, commencement). On the weaker side my elbow starts to rotate upwards as I approach full extension. I was aware of this but what I didn’t notice until recently was that when I held my elbow facing the ground my neck pulled to the side to relieve the pressure. Now I can feel where, when and how the alignment is breaking I can apply the 70% rule properly.

With the hip issue, I have been working on that area for some time and made some modest progress, the other day I wore an old pair of shoes and felt pressure on my ankle when walking. On checking the sole, the wear was uneven and had developed when my hip was less aligned than it is now. So when my hip is aligned, it is like walking across an incline. The shoes have developed an ‘imprint’ of my misalignment and are therefore no good to me now.
