Friction Shoe Adjustment Screw

Question

After these friction shoes 15-104 are installed in the channel and connected to the spring, I don't know what is the optimal adjustment of "friction" by turning the screw either way. Is the goal to move the shoe to anywhere and it should stay there? How hard should it be to move the shoe up or down? I've also seen videos where silicon spray is sprayed into the shoe channel and wouldn't that make it slicker or after lubricating the channel the shoe should STILL stay wherever it is left? Thanks.

Thanks for posting. I'd advise just positioning the friction shoe where the original was located in the jamb track, then tightening it until it stays put. I wouldn't overthink this otherwise, nor would I lubricate it, though a silicone spray can be used to clean window tracks in general, if needed. Let me know if you have further questions.
