Hi Neuromuscular,
Simply put, the stance phase has been validated by peer-reviewed research...the others have not.
I did test the APAS fairly and i resent the insinuation that i had preconceived ideas - have i not always provided you with dialogue? How many people put the time and effort into talking at length about what you want to talk about?
You still haven't tried the stance phase as per the research for 2 weeks yet have you? Are you too biased to try it fairly?
