Thanks, Rob, for reviewing our study. As you highlighted, the key lies in testing under 'constant' conditions. We tried to test the effect of variable practice even when the test itself had extremely reduced variability. In fact, the group you refer to as the control group did constant practice. Although we probably shouldn't have called it that. As you correctly point out, every time the participant picks up the ball, they do so in a slightly different way, they never repeat the same range of motion…, and even during the final throws, they might be more fatigued (not measured) or even more bored. So, we should have called it the extremely low variability group… Despite several calls to consider the characteristics of the skill and the learners when applying variability, few studies still address these variables. We've gained valuable insights from this experiment, and hope our new study, which dives deeper into this issue, will offer more and better. Coming soon ;-) Thanks for sharing your perspective.
Rob we haven't met but I want to acknowledge your contribution to the field with all the podcast and youtube episodes that you so generously share with everyone. This type of bytesize video/podcast research paper overview and critical discussion is a gold mine for studenta, practitioners and researchers alike. I've been following your channels for a number of years now and it is by far one of the best examples of knowledge transfer and dissemination that anyone can find and that I share with my PE student teachers. Keep it up and thanks so much for all your generous, rich and kind contribution 👏👏

Same feeling
Really appreciate this. Thank you.
