70%: static vs. dynamic

I’m sure this is obvious, but I figured sharing it since it might help others.
I’ve been too dogmatic about the 70% rule. Thinking that it’s something that is static rather than a dynamic that allows you to progress.
I don’t quite know how to describe it except that the mode of thinking is that, say in the lifting up of the arms opening Heaven and Earth qigong, where I would arrive at a position that was 70%, it showed me outwardly how I would inwardly equate that with freezing myself to that position, forever. Not slowly progressing, 70%, as things naturally move along and open up/etc., but, maintaining a dogmatic, static viewpoint on what 70% really means. As if that was what the 70% principle really meant.
This really applies to the meditation side of things, but I’m really glad that the qigong and tai-chi really pointed this out to me; I could have really been stuck on this.
