Alan,
Here is how I look at it. IF, you have good, repeatable form, then you will have good (tight) groups (somewhere and regardless of equipment -- within reason). Once you have that, a good tune will help with those groups being in the middle (bull's eye).
I do not understand the common "forgiveness" question. If you shoot a poor shot, you should "forgive yourself" and press on with the next shot. IMO no equipment set up or configuration can "forgive YOU" only you can do that.
IF you make a well executed shot WITH tuned equipment, no forgiveness will be necessary!! IF you screw up a shot, the equipment OR tuning CANNOT forgive you -- only YOU can do that.
There is no magic wand that can be waved to fix a poor shot.
"forgiveness of form oop’s" No such thing, IMO.
