Its Me

When I try to use the config file to change sensitivity it never actually changes any of my sensitivity settings or at least to the same sensitivity that i had input. I put the game settings file on read only so I'm not quite sure if I am doing something wrong. Here is how I'm attempting to convert sensitivities: http://prntscr.com/g8cd43 Also another question, Should i be using 360 degrees rotation, monitor distance, or viewspeed to get the correct sensitivity.
