Said it before, will say it again. All the theoretical pragmatism in the world is worthless without the skill to create and apply the package (whether it is a unclipped keg shoe or a 3/4 fullered, hand made straight bar, deep seated, toes rockered, clipped, etc.). You can read all the books, attend all the lectures, and pass all the written tests, but until you can get it on the foot, as accurately and precisely as you planned, you failed your plan. Anyone can argue the theory, but it is hard to argue the skill. If you can consistently fit a shoe with a dime's width expansion and extension, you can consistently fit one with a half inch of both...or however you so desire. The 'standard' is arbitrary. Being able to produce it (or whatever you determine beneficial) reflects your skill level. Therein lies the benefit of contests...skill development. How one chooses to wield those skills, on a foot to foot basis, is part and parcel to his/her own convictions...and convictions are like distal sphincters, we all have em'.
