This is a great topic! I collect scorecards and have quite a few interesting ones. Here is one from NC that I like. Nice large print, colorful and I especially like the hole diagrams with some need to know yardages. Lots of space for scores and notes. i would have to give this at least an 8.
The timer rule exists specifically for a ball overhanging the hole because of the possibility that it may fall in if you wait long enough. There’s no reason to just stand around and watch a ball oscillate slightly otherwise.
He could have marked it or he could have just tapped in, both for par. The penalty is simply the additional stroke he should have taken to hole out because he waited too long.
If the ball wasn’t marked and it was moved by natural forces, it has to be played from the new spot.
If it was lifted and replaced and then moved, it has to be replaced in it’s original spot.
A ball marker has to be directly behind or to the side of the ball or a measured distance from the original spot of the ball. You can’t just eyeball the marker a couple of inches from the ball.
