Need some help with calculator

Hello there! I am not understanding some settings and was wanting some clarification. I watched a youtube video by stodeh about using the horizontal monitor distance to accurately emulate your preferred mouse sensitivity from game to game. When I do this however I find the sensitivity varies from game to game and is generally faster than what my reference game is which is world war 3. When I use the 360 conversion however I do find that my sensitivity is consistent. I'm just wanting some clarification on the preferred way to accurately translate these settings from game to game or if I'm doing something wrong. Thank you!

For hipfire 360 distance is a perfectly viable option, and it might even be for ADS if it doesn't zoom too much.

Matching FOV is the best way to get an identical sensitivity, but it isn't possible in all games. For those where it's not possible you have to choose which method to use as you can only match one aspect of the sensitivity. There is not one method that is best however, it depends on what you prefer.

For higher power scopes however you need to use another method, which one depends on your preference.
