bed/probe height & global offsets

Okay I think I'm over thinking this, or missing something. My probe is a BL Touch, when I do G30F200 it returns 510.575. this is the distance to the probe tip. Since its Gcode would it know what I have in the firmware for the probe height and do the math for what it thinks Z0 is? Or is this just the height when the probe touches and I still need to find the offset? (G30 Z???)

this is all an attempt to resolve whats in the picture, this is with DELTA grid probing set to 9x9 grid. it seems no matter what I do its always off. So I want to find my bed height, then level manually as best I can since there is no built in adjustment for the bed I'm using shims under it where the bolts are. also if you look to the bottom right you will see the results of the jerky behavior when its printing a skirt for a round object. the test circle was set at 250mm here, but it does it with smaller circles too.

I have a lot more rolling around in my head, but I want to keep this simple and move on from there in case other assumptions are incorrect. You know what they say about assumptions, lol.
