While we're at it we should ask Jean van de Velde how hard it is to make bogey on 18 at Carnoustie when you have to.
I think there's a difference between a "hard bogey" and a "hard bogey when you're trying to make something better than bogey". My guess is that even Van de Velde might say it was an easy bogey if you're trying to make six. His problem is that for reasons only known to him, he was trying to make four or five.
For example, I could walk off the par 3 second green at Kingsley with a four every single time if I was content with making a four there. Just dump it right in front of the bunker, chip to the big part of the green, and two putt (which I did twice this weekend unintentionally). But I'm trying to make par or birdie there, and that can lead to bigger numbers if I miss in the wrong spot. On the other hand, 15 is actually kind of a hard bogey even if you're trying to make no worse than five, because the green is narrow enough that leaving yourself 50 yards short in two and pitching on can still result in a ball rejected from the green. And hitting right in front of or to the left of the green can leave a difficult chip or bump that's easy to screw up. Even playing for five there, I'm likely to walk away with six a not insignificant number of times.
