Reminds me of this startup that makes deformed football (soccer) balls for training [1].<p>In [1] the founder calls it "differentiated training", but that doesn't seem to be an established term in English. There's a wikipedia article on "differentiated instruction" [2], but that seems to be specific to a school context. I only really found information on it in German, e.g. [3].<p>[1] <a href="https://www.zdnet.com/article/qa-mario-sinnhofer-on-rethinking-the-soccer-ball/" rel="nofollow">https://www.zdnet.com/article/qa-mario-sinnhofer-on-rethinki...</a><p>[2] <a href="https://en.wikipedia.org/wiki/Differentiated_instruction" rel="nofollow">https://en.wikipedia.org/wiki/Differentiated_instruction</a><p>[3] <a href="https://soccerkinetics.de/differenzielles-lernen-fussball/" rel="nofollow">https://soccerkinetics.de/differenzielles-lernen-fussball/</a>
This article loses a lot of impact by focusing on an all-or-nothing task like shooting a basketball. Why would you practice shooting at a wrong size/wrong height basket at all? There are no points for near miss and you make enough shots in a game that it's a statics game anyway
