For Battlefield 1, Im using the tool to find out my 360 rotation to inches. When i enter all of my info, solder sens which is 13%, 1080 resolution, 74 FOV, 400 DPI, it tells me that my 360 rotation is 16.0286 inches. however when im in game it takes the whole length of my mouse mat to do a 360 (zowie GSR) which is 18.9 inches. why is this? is something wrong? where is the discrepancy? any help is really appreciated.
