As far as I'm concerned the critical factor is sight distance and braking distance. There is a huge difference in my speeds in the woods in Arkansas compared to my speeds here in the Texas Big Bend. In the woods, sight distance around/through the corner is often limited while here it is often the case that sight distance is a long way through the corner even when the geometry of the curves are the same.
The other factor is that different states, and in some states different counties apparently use more conservative or less conservative criteria is posting those advisory signs. I normally judge corners without really looking at my speedometer, but the ones that say 10 or 15 or even 20 usually cause me to check my entry speed with the speedo.
