Hello, I'm wondering if anyone out there with the NS Pro 880 AMC shafts can help me with a measurement?

I currently have a set of AP3's with the NS Pro 880 in Stiff, hopefully someone has them in Regular. If so, in Regular on the 7 iron, how many inches is it from the top of the ferrule to the first "step" on the shaft?

I'm looking at another set that the owner says has been hard-stepped, but doesn't know how many steps.

With the measurement I described above, hopefully I can figure it out. Thanks!
