breaking 100/90/80 etc.

simple question, if my best score ever is 47 on 9 holes, my best 18 is probably 110, have I "broken 100"?

(don't get to play a lot of 18 hole rounds is why I ask)

no, but you've broken 50 on 9, similar, but not quite the same

that's what I figured.. "sorta, but not quite". :)

I shall endeavour to get under 100 Monday on full 18 then !!!

good luck...

what is par? i was almost impressed with myself last year reviewing my scores when I saw that I had posted a couple of mid 90's scores, then i realized that par was 65 on the course... talk about being deflated!

I also play on a 9 hole course frequently enough, and it is only a par of like 32. So any score over 41 doesn't really boost the ego any more either :0)

No - breaking 50 for 9 holes is not the same as breaking 100 for 18.  I also play mostly 9 hole rounds.  I play 9 once or twice a week but only get out for a full 18 5-6 times per year.

I have scored as low as 42 for 9 holes but my best 18 hole total is 94.  For me, the difference is focus.  It's not that I get physically tired on the back nine - it's that I lose focus and become "mentally tired".  I think if I played 18 more often, my 18 hole scores would come down - it's just that I'm used to focusing on golf for 2 hours at a time.  In a sense, it's the same principal at play that makes it much harder for pros to shoot 4 low rounds than just 1.

re: breaking 100/90/80/etc.

websites like OOBgolf will let you calculate a handicap based on 9 holes at a time.  It isn't official, but for ranking yourself against other golfers and knowing where you stand, I think if the scores you say are legitimate than you will know where you stand.
