@jsgolfer had a flop shot he executed well from about 20yd on a direct line from the camera behind @DeadMan. There is a pic somewhere. It landed softly in a similar spot to where your bunker shot did, in fact.
Like you said you expected, it rolled out a ways down that slope.
Again the camera doesn’t quite show the undulation as dramatically as real life.
I think it's because the perspective of the photo with the shadows makes it look like they're chipping from an elevation above than the surface of the green. In reality they were about level with the edge of the green, and then it sloped away from them towards the bunker from there.
I'm still surprised that the bunker shot ended up short of the hole. With how much the green ran away from that bunker I thought I'd still be 5 feet past the hole even though the ball landed in the rough before trickling onto the green.
