Max takes a look at run values around the plate. This is Max's first THT article, and he's only been writing in English for a few months. His work had been almost solely in his native Italian until recently. Take a look, it's very cool. I've asked Max (who I had the pleasure of meeting last May at a PITCHf/x Summit) to contemplate my layer and slice borders in light of this research. The next rev of that could indeed reflect Max's findings. I've asked him to look at vertical and horizontal positions, across all pitch types. Hopefully he'll publish his findings.
