are golf rules always good? lol not at all. Golf has the most antiquated rules of any major sport.

Also many basic rules made in the beginning were not created in the spirit they have been warped in to.

also, I don't see there being too big a problem with golfers keeping eachother's score, I don't think that's the issue. However, why is there a need to dq when there has been an error or, with what's common with tv rules officials nowadays, a modification of the score after the card had been signed.

At the time the score was right, how does having a penalty added after make the first score wrong? It just changed from the time the card was signed

Train ? Hell, most anybody can record and add up single digit numbers !!!

Who needs PAID scorekeepers ? There are 1,000 volunteers to do most everything at a PGA Tournament. (Presumably so they can give the 55 kazillion dollars they do to charity ???)

The scorekeeper doesn't need to WATCH to keep track of their scores - the players simply tell the scorekeepr what they made after each hole. After 18 the offficial scorekeeper checks with the players to see if they want to double-check the scores. If so, the do. If not, the scorekeeper hands in the official scores, someone checks the arithmetic and that's that.
