Best Answer
From playing with the system a little myself, 20% sounds close for day to day use and not putting in much dedicated practice. As with most mental math (and most math in general) speed will increase based on practice. I enjoy that there are only a small number of techniques used for a large number of applications, rather than a large number of application specific techniques to memorize as in some systems.
The more extreme example mentioned sounds more like a stage demonstration than an average improvement.
