Did you read the Silca blog post?
It was not about their calculator.
They measured. You could contact Josh for more detail. The very important point of that article? There is very little lost being slightly under pressured but a lot lost being slightly over pressured for the conditions (lousy roads).
I found that 100 psi was the perfect pressure for my bike and my weight using 26 mm wide (actual width) GP5000 tires. Silca says 89 psi. Low and behold, I found that my pressure gage on my pump was reading 11 psi high. According to their online calculator, their suggested tire pressure is not dropped all that much with lower weight.
