@dc42 I am happy too, thank you! I had been bouncing my head off a wall and digging through the forums looking for so guidance before I posted. Then after I said let's give this a shot and dumb luck won the day. I was only using mesh as a tool to see what my delta calibration was effecting.

okay, I think I solved my own problem. But any feedback or input is welcomed, good or bad. So first I bumped my bed.g probe from 7 to 13 points s6 which took my mesh deviation from .174 to .054 and min/max from -.512/.363 to -.140/.114
NOTE: I am using a boro bed and have put a straight edge across it with a light it is "almost" perfectly flat. I am very happy with the results

With that I went all in, adjusting my bed.g probe point amounts / from s6-8

bed.g 13 points @ 112radius 6 factor
g29 - 61 points probed, min error -0.140, max error 0.114, mean 0.004, deviation 0.054
m666 Endstop adjustments X1.59 Y-2.48 Z0.89, tilt X0.00% Y0.00%
m665 Diagonals 288.000:288.000:288.000, delta radius 139.404, homed height 230.635, bed radius 110.0, X 0.321°, Y 0.112°, Z 0.000°

bed.g 16 points @110 radius 6 factor
G29 61 points probed, min error -0.078, max error 0.078, mean -0.001, deviation 0.036
m666 Endstop adjustments X1.64 Y-2.37 Z0.73, tilt X0.00% Y0.00%
m665 Diagonals 288.000:288.000:288.000, delta radius 139.543, homed height 230.643, bed radius 110.0, X 0.479°, Y 0.073°, Z 0.000°

bed.g 16 points @110 radius 8 factor
G29 61 points probed, min error -0.053, max error 0.064, mean 0.007, deviation 0.023
m666 Endstop adjustments X1.38 Y-1.34 Z-0.03, tilt X0.59% Y-0.70%
m665 Diagonals 288.000:288.000:288.000, delta radius 139.487, homed height 230.644, bed radius 110.0, X -0.051°, Y 0.098°, Z 0.000°

EDIT: Just ran my first test print - the first layer...perfect all the way around the bed.

quick update - I made a new bed.g with more points s6 and ran calibration once and then ran a mesh and this was the result.

I converted my delta over to duet 2 wifi, smart effector, mag ball arms. I ran delta calibration and followed to documentation. I ran it 6 times and kicks out deviation of -0.000 , 0.017 +/- .05 on the latter. I ran mesh bed leveling to see what it looks like and it is not good. I then went back and set my probe offset to 0 and measured the trigger height of each point in delta calibration and offset those points z in bed.g . and it did not change my mesh much at all but at least it is consistently probing those areas correctly. any help guidance is appreciated! Please see below my mesh's I ran 4 times and they are identical, and my config / bed.g

; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)
