Sitz Bones "parts"

[Miranda]

I have read many things on here about our sitz bones. I've searched, and think I remember reading something about different "parts" of our sitz bones?

I'm not sure if I'm still hitting my saddle with the right "part" of my sitz bones?

By this I mean, if you look at a diagram of pelvic bones, where our girly bits are, there is a bell shaped curve. I know the sitz bones in this one dimentional pic are are the base of each low point of the curve.

If I am feeling this correctly on my new saddles I'm trying, I think I am still only hitting somewhere just on this inside of this curve... versus the exact tip of the sitz bones? It's pretty close. Maybe it's my riding angle, vs sitting straight up in a chair pressure sensation? btw... I did vary positions between hoods, drops, and slide the saddle forward some too... also riding without chamois for the test spin to not mask the pressure, beside my trunk junk fat

Prior to this I have been riding my pubic bone I figured out with the help of TE. What I feel is definately an improvement from THAT. I honestly don't know what true sitz bones pressure on a bike is suppose to feel like? Pretty sad. Maybe I am indeed on it? Thx for any help!
