With regard to pitch marks not being repaired, I read somewhere that one of the main problems is people only look in the immediate vicinity of their ball, thinking they can stop the ball dead every time when in reality the ball always rolls on more than we think.
I’m not a sweary type on the course, but I can guarantee the air will be very blue whenever I arrive at a green and find a pitch mark within a few feet of the flag, which happens far too often. There’s absolutely no excuse for it.
I do agree that some do tend to limit their search to the immediate vicinity of their ball. What they should be doing is simply repairing any pitch mark they see, not just looking for their own.
