Is 0.41 your in game sensitivity? In that case you should put that in the multiplier 1 input box instead. Sensitivity 1 is the option to account for the total turn speed reduction of the armor/helmet/backpack you use.
Also, DPI Wizard will have to clarify how it works but since the sensitivities in eft are all over the place you might want to pick one to use as the base just to be sure instead of All since the conversion can only be correct for one of the sights anyway.
