New measuring technique
I have noticed from my experience that it is possible to “adjust” the measurement of your length with the ruler to get results you wish to see or expect by adjusting the angle and pressure you apply to the ruler. To remove this inherent bias in measuring and to get statistically more accurate results, I think it would be a good idea to use some kind of unmarked strip of cardboard or thick paper to measure your length by marking the length on this blank ruler and then measuring the distance to the mark, rather than measuring the penis directly. You could do this 3 to 5 times and get an average. I would do this to prevent myself from seeing imaginary gains.
