Hello, I'm not quite sure how to use these calculators, if I use 800 dpi with a normal windows sens and a 1366:768 resolution that means it would take me 1366/800 inches to move from one side of the screen to the other correct? and that is equivalent to a 180 so a 360 would be about 3.4 inches correct? How come the calculator is returning values for me that attempt to put it at a value of about 6 inches per 360. Also how come the number is variable, some games result in a 5.8 inch per 360 others are above 6. Im trying to get the settings correct for all the games i play but I just can't seem to get it right and I need help.
