Tdk6, Mind if I take a stab at your question?
Let's consider a car on an ice covered road traveling at 25 kph . (He's European, so no mph)
This driver wants to make a left turn into the narrow entrance of a ski area parking lot.
This driver considers two clear options to make his turn:
coarse guesswork to determine the
Option 1) He can guess at the best moment to start his turn and rapidly yank the steering wheel to the left. He'll be using
amount of steering-wheel adjustment to make hoping it will be about right.
He'll fully expect to make more coarse adjustments as the car will veer somewhat randomly to the left. He'll make more coarse guesswork adjustments to manage ongoing direction as the car fish-tails wildly. Eventually, the car will be pointed where he wants it to go.
Option 2) He wont guess at anything and instead will progressively and controllably
rotate the steering wheel to the left. Since he'll be using finely controlled motor skills
to rotate the steering wheel he'll be able to continuously guide the car in a fully controlled manner to the left. As the turn progresses he'll make more small, fully controlled adjustments as the car increasingly goes exactly
where he wants it to go.
I think this is the same idea as gross, largely uncontrolled steering in skiing vs. fine, fully controlled steering.
Coarse steering patterns generally employ large muscle groups that simply overpower the ski and shove its tail somewhere close to where it will do the job. The snow will likely resist this lateral shove and then suddenly "give way" all at once rendering any planned
amount of tail displacement nothing more than a hopeful guess.
Fine steering patterns employ both large and small muscle groups to controllably and progressively guide
the direction each ski is pointing. (ILS does this quite well.) Steering efforts like this allow the skier to progressively modify each
ski's current aim, even independently if they so choose.
Use of steering patterns is independent of Turn Phase (or whatever location classification you prefer). We can shove the ski around (or guide the ski around) just as easily at turn Finish as at turn Entry or turn Apex.
