Ok, how many times to I have to tell you lol.
It is not the same, and the simple reason is because your 1st shot, was not notched, re-aiming with your thumb doesn't make it the same as re-aiming to this angle again by notching, because you are NOT GUESSING, even while re-aiming with my thumb I still have to guess where to go from where I guessed the 1st time to correct it, so the whole time, I am still guessing.
You just don't get it lol.
