I agree with the OP that the cup physics are not right but in saying thst they were not right before they "quote" fixed it.
It seems like they went a little overboard to prove that the game now has lip outs.
The new camera angle following the ball to the hole is a nice touch, but it too in my opinion is a bit flawed. To me camera is a little late behind the action and you don't get a good look at the ball arriving at the hole. The angle should be a bit higher, and as I said zoomed in sooner.
I haven't tested the cup physics yet, but prior to the update I could set the distance to 25 feet for a 6 foot putt and it would go in. I could set it substantially higher and have it pop up and sit 6 inches on the otherside of the cup.
The update is better, but far from perfect.
