I reckon air gunnery is a lot like golf (I don't play, to many nasty 70's flash backs).
I think it's a good analogy because a lot of people can understand and relate to it and it involves many of the same factors.
However good you are (mere mortal) you just know that if you tee'd off against the likes of Tiger Woods, you're stuffed, he's so far removed he could be from a different planet. However good you are, it's only when you play against these God like beings that you appreciate for all you're skill it just not even in the same league.
So there you are on the putting green, playing for a million dollars, You can place you're ball anywhere on the green but obviously the closer you get to the hole the further you have to walk, the longer it takes to place you're ball and take you're shot. If you play against a pro, he might just place the ball down at the edge of the green and take his shot straight off, but then even Tiger might miss. If you're a normal person, you're going to try and get as close as possible to the hole, the trouble is the longer you take the more opportunity Tiger has, the more nervous you become the more rushed you're final shot etc etc. The further you are from the hole the more you have to take other factors into account, wind, slope, distance, spin etc etc. Now add in the factor that your opponent is playing on a different green that you can only just glance at behind you, you're only advantage is that you've got a couple of mates also trying to get a ball into the hole.
So like I say, I reckon air to air gunnery is just like golf.
