Many of us who have shot considerable offhand rifle shots press the trigger as the crosshairs are within acceptable accuracy and moving toward the target center, then hold that level of press if they go past without the rifle firing. The process may be repeated once or twice for a shot, but if we feel unsteady due to lack of oxygen or tired muscles, we release the trigger and lower the rifle.
To the same extent we do the same when shooting from various field positions. The secret is to not jerk the trigger, but to press. When plinking and doing rapid firing, the press is faster and within the "wobble zone" that you mentioned.
Handgun shooting is entirely different and follows your "wobble zone" technique, pressing the trigger in a continuous movement, once the sights have settled into "the zone".
