And apologizes if I come there a bit late, but... in my mind, 100% means that the output file is the exact reflect of the input one. So, importing a picture with 45% compression ratio and exporting it at 100% would result in the same 45% picture that was input. And exporting it at 50% would result in 24.5% output picture. In the facts, I am not sure this works that way.
