matching your scopes 360distance wont work when converting scopes to other games ( because no 1x scope will have the same fov in game a and game b thus your actual sens will feel different even if you have the same 360 ) , if you want uniformity the 1st thing id suggest would be to stick to native res in both games ( or stretched in all but that isnt always achievable or actually worth it ) that should make matching hipfire much easier ( both x and y axis feel should be the same if you have the same aspect ratio / resolution at the same fov ) .
what dpi wizard did in the link is , matching the scaling to match your r6 sens if you are willing to adapt changing your r6 settings to match a scale would likely result in a more uniform experience.
id likely go with something like that https://www.mouse-sensitivity.com/?share=dc2ae512840a77ce956a3154b36e7ed4 the scopes wont have the same distance but once you get used to it there is a sense of uniformity ( independent of your scopes fov ).
