i never once said this was a way to tell if the file was corrupt 100% or not. as a matter of fact i said there is no way to tell. ALSO, i said that there is an expected outcome that is measured from know good files. as long as you fall within that range, it is an indicator the file /MAY/ be good, NOT 100% corruption free. your trying to prove a point that everyone knows.

furthermore, you can run statistical ananlysis, and get the percentage inwhich each byte character (0x00 - 0xFF) show up in the file, and likewise... if it is below or above a certain range, you can just about put all bets the file is corrupt :)

anyways, im nto going to argue with you anymore. i know what your talking about sir, and i completely understand what you are saying. there is no true way to tell, even if the entropy range, percentage analysis of byte characters, std dev are within the known ranges. but if they are within this certain range sir, i would put my money on the file being "ok" or corruption "free".

If this didnt work and did not help, then there wouldnt be older tools that people still use to this day. all i am trying to do is replicate these tools/functions. The main goal of this method is, if any of the calculations fall outside of this expected range, then it should make flags go off in your head and signify furthermore that the file is no good and if you use it, then you will surely be messing up. :)
