Photoshop Brush Settings – Making Thick-to-Thin Strokes on Tablet

Hello to the Adobe Community! I have university assignment brush settings adjustments due in two weeks. One of the exercises in the textbook requires me to do something that—when followed through—seems very outdated or no longer existent for time gap between the textbook’s publication date of 2014 and Photoshop’s 2019 version.

Specifically, the textbook ordered me to make a hard brush jitter its size at 0% on Pen Pressure, but that’s not all. Supposedly, this would mean that my tablet would have been able to progress from the thinnest stroke weight to full thickness as I apply more and more pressure bit by bit (for the lack of physics terms). It did not work. I followed this all the way through several times and tried more times with difference Size Jitter values, but the idea conveyed by the book never worked in practice. Making the squiggly lines never made the difference, either. Does anybody know if it still is possible to use Pen Pressure on my tablet to generate strokes that progress from thin to thick? If so, how do I do it properly or what am I missing?
