Standards and Practices
What seems to me to be in order is a reference guide. What is needed is a commonly accepted standard.
If there is a preferred method to perform exercises or, most importantly, it would seem, measurements and results, then someone should provide examples. Visual aides are extremely useful to members for whom English is not their primary language.
Gandolf has the means, ability, equipment, and dedication to attempt this.
Thanks for considering it, Gandolf.
