I've had maybe 4 or 5 no bogey rounds. They are far more rare than a round in the 60's. A few years back in the first round of our club championship I shot 72.....18 straight pars.
Once on an 18 hole round, 65 with 5 birdies.
Once on a 9 hole round, 30 with 5 birdies. I may have done it on another 9 hole round, 9 pars or 8 pars & 1 birdies. But the 30 is the only 9 hole score my mind let's me remember.
A dozen or so, but I usually don't score as low as rounds where I have a bogey. It seems the aggression that gets me the birdies also comes packaged with a bogie or two.
I have had 4 rounds of 66, and all of them had at least one bogey(one them had 3 bogeys). I think my lowest bogey free round was a 69.
I've had a couple bogey free rounds also, but not in a while. Even when I'm striking the ball very well, I usually have a bogey early in the round, and then can make a lot of pars and some birdies to get rid of those bogeys. The elusive "bogey free round". Just another reason to keep spending time and money on this messed up game.
On a full course for 18 holes...my goal is no double-bogies. I've had a few rounds with only one double, but that's as close as I've come to my goal so far. I guess it's true...I really don't play as good as the pros.
Only through 12 holes then I got an 8 on the par 3 13th! Then I got 3 bogeys after that for a 78 (par 70 course but a challenging par 70 course). What a round killer! Especially when I didn't make 1 birdie all day. After parring the first 4 or 5 holes I was concentrating so hard on saving par that I wasn't aggressive enough on birdie putts. This was also my best start ever and my bestt round ever even with that darn 8. That will snap you back to reality quick. Word of advice, take your medicine and the stroke penalty instead of trying to hit out of an uphill lie behind trees when you ball is lying on loose hay. Or just hit a better tee shot! LOL
