Yes. The OP made a sweeping statement that has some merit but is not entirely accurate.
eg. There's a Par 3 on the back nine at Kinloch (NZ) which is a top 100 course. I wouldn't aim at the flag, I wouldn't even aim at the centre of the green, heck, I wouldn't even aim at the green, I would actually aim to miss the green right and back myself to get up and down.
The Par 5 1st at Riverside Oaks has a green that is 70 metres wide, biggest green in Australia, if the flag is cut short right, do you really expect a single figure marker to aim 35 metres left of the flag with a wedge just because it's a GIR?
Extremely fast greens are another example where you must keep the ball under the hole at all costs, even if it means missing short.
I'm sure the OP means well, but I would like to think he could explain how good players manage the way they attack or play a hole a little better than he has.
Guess we'll have to buy the book!
