Head-Trained Spur-Pruned Grapes

Does anyone have experience with Head-Training Spur-Pruning Grapes?
I would like to do this with a table grape this spring, so I’m studying up.

Head-training spur-pruning (HTSP), aka Goblet or Gobelet, is a very old system for grapes. It produces a free-standing grapevine that looks like a small tree.
