I've only been playing for about 8 months, but I've seen comments about the OOB areas.
Andyson, who has a lot of knowledge on different aspects of WGT (IMO) has mentioned about ".. The mini-map border is normally the OOB boundary. " (* see link below)
When I look at the min map during the replay it looks like the ball lands just at the edge of the map, maybe even beyond it ** a tiny bit, then it rolls some more.
The ball is visible on the main play screen but that looks like it is very close to the suggested 'Out Of Bounds' area, as shown on the mini map.

I'm not sure if the animation is able to show a ball go BEYOND the mini map, etc. so it could be it went outside, and past the map's edge, but the animation shows it right on the very edge of the mini map. (which, still, in itself, is a very close call)
Naturally, David, I know what you mean because I can see the ball clearly.
