Notable Features

Generally, there are good features in Jessica Schipper's action. It would be worthwhile to speculate what would happen to her stroke if she attempted to achieve a greater degree of "elbows-up" early in the pulling phase. That would have the potential to extend the length of force-application as well as increasing its magnitude, particularly in the latter half of the force production.
