Sean,
I think we're saying the same thing, in a way, but I think you over-estimate the predictability of shots and are unwilling to accept as random (lucky) things that, to all intents and purposes are. Let me put it this way. Put a ball on a tee at Kington (say the 7th tee) and have Iron Byron hit driver. The ball may well land in a micro-undulation and take a deviating bounce. You appear to argue that if Iron Byron hits another ball from the exact same tee, with exact same impact parameters and the "exact" same wind you'll get the same result. The fact is, you won't. That wind is turbulent and un-modelable on a micro scale. The two balls will, inevitably, meet different conditions as they pass through that turbulence and may land, say 12 inches apart (in fact I suspect the dispersal due to turbulence could be significantly more than 12 inches, I'd be happy to believe yards). Even that 12 inches can make a very big difference to where that ball ends up.
I know you don't want to describe that as luck but I'm afraid that the very, very best prediction that physics can make for where a ball ends up will have a probabilistic (sp?) element to it and I'm happy to call that luck.
I think that's a good thing on a golf course, by the way.
Of course these effects have much less impact on the eventual resting position of a ball on dull golf courses without small dimensioned obstacles.
Regards,
Mark
