This is very strange, as this is a multiplier. Meaning 1 is the same sensitivity as hipfire based on the scaling setting. So with legacy it's MDH 0%, and with relative it scales with the relative amount. So relative amount 1 is MDH 100%, if you set the MouseScopedSensitivity to 0.5, it will be twice the distance of MDH 100%. 0.07 is extremely slow, there must be something else affecting the sensitivity here, could you attach or PM your settings file so I can try it directly?
