Probably true.
No such thing unless it's a game for total hackers playing golf and they made their own rules up. Golf is based on PAR. You have par 3's, par 4's, and par 5's. The number of strokes that it SHOULD take for that given hole. Less is even better and they're called a birdie (one under par), or eagle (two under par).
There are different names for "over par" but it doesn't matter because I'm not going to take time listing them. What DOESN'T
happen is a "MERCY" number like you stated about nine strokes. Not in the official rules of golf.
Might have been a local rule. Might have been nine over par too. I don't know. They were talking about Mulligans and such too, which seems to be a mercy rule.
A funny, I was visiting my cousin a few states over. Her husband came in from playing golf. He was pumped! He had scored two eagles, a sprinkling of birdies, had a great day. Trying to share that with me was like trying to tell him I ran a sixpack.
It wouldn't be called an approach shot. One stroke for all the marbles is a PUTT. You play it with a putter and try to knock it into the hole. It might be the same as having 4 nine foot pool tables placed end to end stretching out to 36' with no end rails to stop the CB. It would also have wood under some of the legs to make it roll uneven to the right or left which you'd have to calculate when striking the CB to make it break into the hole of the last pool table. That's what putting on a green at a golf course is all about. Actually, there are 18 of them you have to do it with. Some roll fast like new Simonis and others run slow
like old thick felt. Easy, huh?
Anything I know about golf is decades old. I heard the commentators referring to the shot to get to the putting green as the approach shot. My running partner played golf and tennis, worked on golf clubs and tennis rackets too. Listening to other people talk or the rare times I was trapped into watching it on TV are the only times I heard about or saw golf. I might watch the final few holes or a playoff by choice. I like to watch people under pressure regardless of what they are doing. When there is enough money between first and second place to buy a house and they are trying to get a funny looking jacket it gets interesting. Kinda like olympic sports. I may not care about the sport itself but the competitors can be interesting. Remember Olga?
I did watch hours of golf one day. I think it was a major event somewhere in the UK. There was a huge swag in the green, closest thing I can think of to describe it would be when the big ocean swells are rolling in. They decided it would be a good idea to put the cup maybe five feet down from the top of this trough. You either holed out or you watched your ball roll back and forth awhile. When you got to shoot again, uphill from the bottom of the trough, you made the putt or you watched your ball roll back and forth again. I think some players went five or six over on that one hole. They did move the cup again after that day's play, no more fun for spectators! One or two players did hit that cup from fifty feet out or further, the best way to not go gray, grey?, or bald playing that one hole!
A few balls managed to hang on the grade but then a player was trying to read a severe side to side grade. They had to hit the ball hard to fight the grade but then they had to center the cup perfectly to get the ball in the cup. Lip the cup and watch the ball roll back and forth awhile.
I'll match your tough putting greens with dirt tracks. Ever changing, very tough conditions sometimes, and you are the ball! One track had a habit of things coming up out of it while racing. They put whatever was handy to rough in the shape of the track banking and then put a little dirt over it. The entire roof of a car came up in a turn one night, fortunately it was firmly attached to the car beneath it! Another night a piece of wood was coming out of the track. When somebody centered it we discovered it was a huge stump! A wrecker pulled it out leaving a hole in the track the size of a small car. No way to fix the track so it was just a matter of stay out of the hole in between turns one and two that night. Mostly people came to that track to fight, squeezing in an occasional race between fights. The Frog Pond as we called it was a barrel of fun! I have to admit if I wasn't with a car I sat in the stands with both hands firmly in my lap!
Another track, the track developed washboard style ripples for well over a hundred feet in a big sweeping 180 degree turn, technically turns three and four. For several months I tried to find a car set-up and path through the washboard. I would be working my steering wheel all over the place trying to find some bite with the front wheels then when I finally got to the other end of the washboard my car would alter direction drastically depending on where I had the front wheels pointed which I of course had no idea about until I found traction. The only solution I found was to pick the spot I wanted to come out of turn four at, aim at it going into turn three, then just hold my steering wheel straight while the washboard had it's way with me and the car. It still flung me out the other side out of shape but at least I knew where my front wheels were pointing!
