Forget the A-10 for a moment, use a strike eagle carrying 12 mk-82AIRs. Due to the fact that an enemy may have LR defence systems everywhere and EWR systems it makes sense to do a run it at low level. A pop up with conventional weapons or CBU's puts you slap bang it what I call the range of everyone ranging from Iglas, 37mm or upwards flak, Zu-23 or similar, and even medium range sams unless your target is next to the sam site. Now remember there's this little thing called reality meaning you don't always have a stockpile of expensive toys, at 300 feet and 5-600 knots there's bugger all that's got much chance of hitting you without barrage fire. (Remarkably it isn't easy to shoot a jet that's crossed your line of sight in a few seconds.) Now you run into the target and release your twelve bombs in whatever way you like. (Pairs, singles, Impact, airburst). The bombs are well behind you when they go off meaning frag isn't a worry. At no time in this aside from the 5-10 seconds needed to track the target do you have to provide a stable aircraft. In a pop up you must climb and dive, especially during climb you're vulnerable, more so if you have the burners going. (At night everyone can see you and IR sams are more of a threat at all times.) If you don't use burners you're going to be slow at the apex of your climb.
EDIT: You don't need to be diving much at all to use CCIP, to use your example of a runway how bloody hard is it to hit if you're dropping lots of bombs.
Also, you were given a link to a document stating that over a 1,000 were used in real life. Attempt to read people's responses before asking the same question over and over again, it merely makes you look like a fool.
