no mean to offend but "seems about right"? do you really believe that you can tell the difference between 4.9 and 5.1 or do you have a method of tracking it... cause i honestly can tell you that it may be my lack of experience or perception but i would never be able to tell the difference unless it was shown to me in some kind of test and.. then and only then... will i feel the difference, but only psychologically...
