Does anyone know the coefficient of friction between cue ball and tip?

So I'm still thinking about the miscue limit mentioned by Dr.Dave, and I'm wondering if anyone knows the COF (static and sliding) between the cue ball and a leather tip (chalked and no-chalk)? If not, I'll do an experiement myself and report up here.

The miscue limit is like pornography. Hard to define but you know it when you see it.

But a rubber tip lets you hit further right? I know it increases deflection and contact time, but you can hit farther with something that has highter COF

I don’t know that. With a softer tip for example, the eccentric aim limit is inside of a harder tip’s aim limit because the soft tip will ride longer. The softer tip will hit the same miscue limit when you start closer to center compared to a harder tip.

Can a rubber tip ride farther? Possibly, but the tip deformation of a rubber tip might be different than a leather tip. If they don’t deform significantly different , I would expect the rubber to slip at the same point. Maybe if a rubber tip’s COF is much higher, there’d be a statistical difference, but I’d have to see the data.

thanks, I'll try that
