The criticism is for the concept of setting up an expectation and a path that is unrealistic and is short sighted. To give this type of suggestion to someone looking for honest information about how to improve is basically Pitching Coach malpractice as far as I am concerned. You basically said, ignore all of the mechanical issues, just stride longer and more consistently, use this grip and throw strikes. What about the drag foot being left behind and not being dragged? What about her pulling her hand back after release and the loss of power this causes? It's simple really, quality in anything takes some time. If it was as easy as you say then everyone would be doing it that way. I know the OP asked about accuracy, and you answered about accuracy, but there is a bigger picture here.
