I was always was under the illusion that 0.0165 m_yaw was the m_yaw used when playing 4:3 stretched in csgo for the horizontal and vertical sens to feel 1:1 and as expected 0.0165 m_yaw was the result given to me in the calculator, although when any monitor size was added the m_yaw figure changed to 0.017976. I would be grateful if somebody could explain this to me and the reason behind it, theres screenshots of both calculations; 1 with and 1 without the monitor size below
