Mesh Grid Offset?

I'm trying to get the auto bed leveling figured out on my delta.
My inductive sensor sits 40mm on the +y axis.
The issue I'm running into is, when I set my radius to like 70, it only probes half the bed.
The whole -y side on zero doesn't seem to get probed.
I changed the G31 offset in config.g, and that's the only place I've run a G31.
What am I missing?
Please post your config.g file.

I was also confused as to how to calibrate the endstop offset, I came from Repetier and the G132 offset tools.
To put the nozzle at X0 Y-20 would require the nozzle to be at X0 Y-60 so it should at least probe that point. To probe X-20 Y-20 would put the nozzle at X-20 Y-60 which is 62.4mm from bed centre, so that should be probed too, same for X20 Y-20. But all the other points on that half of of the bed will be omitted because probing them isn't possible while keeping the nozzle within the bed radius.
