These are all common misconceptions, and are not necessarily something you need to be achieving to hit 80.
Hitting 80 is far more about making sure that you’re not messing up hugely on the course. You need to make sure that your game is strong, and not consistently making the same mistakes.
Triple or double bogeys make it infinitely more difficult to hit 80, so you need to try and keep these as low as you can.
Most people who have managed to hit 80, are either super good at one portion of the game, which they excel in, or they’re pretty good at everything, but don’t necessarily excel.
