Hi Autothrottle,
I cant veiw the link you supplied, but to my mind a pilot would be far better off achieving a kill with the least amount of ammo possible.
If your taking most of your ammo to kill one plane what do you do with the rest of his mates when your done with him.
The second reason for using limited ordanance per air kill or gound target is, it costs money to make them. So to use them in the most expediant way would be the prefered option.
Most of the things I've read or seen in documentories suggest that a 3 odds second burst was about as long as you could get in before you lost your sight picture.
Most guys said they would get off a one second burst if they were lucky, anything longer than that they were wasting ammo.
I'm not sure what you mean by most pilots fired in selvo? this is a term usually used for massed artillary or ship fire were all the guns are fired simutaniously.
the main reason for firing in selvo rather than individually is the combined effect of multiple guns could be considered in some cases to be more effective than say 5 singular shots to the same area.
This could be due to the strenght of the target or because the gun base is moving. This is especially the case for ship fire, were the ship is moving, its easier to sight in and fire all (or as many as possible) guns at once then trying to obtain a new sight picture for each single shot as the ship is moving forward.
For aircraft gun fire, its pretty much short burst or prolonged bursts.
Rockets were fired either in selvo (all at once) or in pairs from aircraft.
