To add to what Form is saying- practicing with tools that allow more precise corrections for misses leads to more precise holds and more precise learning, which leads to less misses while hunting. So it’s not so much about being able to call super precise corrections for misses while shooting BG, but more about practicing in such a way, and with tools that make misses on BG even less common.
To continue the speedometer analogy, if I practice on the track with a regular speedometer, I may figure out that I can take a certain corner at 68 mph without losing control of the car. When it comes time for a race, I’ve practiced taking that corner at 68 mph so many times that it’s instinctive. It’s much more difficult to practice taking the corner with that level of precision when the speedometer only has one mark on it at 47 mph. When race day comes I’d be less likely to make that corner with precision if I had practiced simply by gut instinct using multiples of 47 as my guide.
