So if you want accuracy use camera pwm to get bot to camera center angle, then target centeroid pixels to get camera center to target center.

This post is clear up until the last sentence. What proceedure are you advocating? Are you saying that instead of a straight camera servo value to target distance calculation you should use the target center value in pixels?
If you are:
Does this make a difference if the error tolerance is 0 or 1?
Is this more accurate? What is the math behind it?
I guess the advantage would be that the target does not have to be in the center of the camera field of view to calculate distance.
Any other advantages?
Thanks in advance,
