I see you posted twice. The first guy gave a good reply. When it comes to anything sensitivity wise it's how it feels to you. There's never a right answer because you can only match certain aspects of an old sens from another game. For you there is no calculation. It comes down to trying out different coefficients. My recommendation is try 0 as it's equivalent to MDV/MDH 0% which most people like and is good for muscle memory. If it's slow try 1.78 which is the same as MDV 178% roughly and is good for 16:9. For me i played csgo which uses MDV 133% = 1.33 . So it's all preference and you are kinda on the right track. So when ADS it goes slow to faster in this order (0.00, 1.33, 1.78, some common values) and you'll just have to test, and then you can transfer to other games. Let me know how it goes
