I did test the calibration twice in 2 days with different computers and adresses to find that one day I was 310, and the next day it was 635. That is a big jump that is not logical, but since I know my level from feeling inside I just wanted to test it for fun. To make it short, people already know their level inside, no need for tests. No one can see through your eyes, only yourself can do that. Testing is only for fun, but can never replace real truth from within. But then again, it already stated underneath, do not believe anything on this site. You all have already all your knowledge within, enjoy the exploring !
