Originally, the 15% drop came from the tire companies to whom Frank Berto talked. So Frank then just tried to figure out how to get that value.
Our initial tire testing indicated that somewhere around 15% tire drop was the point where performance and comfort were optimized. Since then, we found that at least for supple tires, even lower pressures don't seem to slow the bike down, so it matters even less. However, even today, the 15% tire drop values from the chart are a good starting point for experimenting with tire pressure...
