If it were 'real' you could hit a TERM consent and the weapon would home on the contrast under the centroid/graticule, just like a Maverick.
Since it isn't, I do indeed recommend a 'fall short, frag long' impact (I've flown right /thru/ the airfield tower with this thing).
Also, contrary to most statements you want to _back off_ the magnification as you get closer, this can truly screw up your apparent approach angles in Z-view and leave you with insufficient maneuver authority to complete the terminal flyin.
X1/X2 is best and delaying your pitch over a _little bit_ can give you a slightly steeper endgame. Be careful how you use the CTRL-Arrow keys as they will occasionally 'blank out' and seem to have hit hard stops when in fact you simply need to repress again.
IIRC, I modified the training mission loadout to include two of the AGM-130's instead of 2 JDAM and this helped me "practice, with an expensive missile".
Watch your turn away maneuver too. There is a short 'bowling alley' clear lane between the mountain ranges but if you go full-range you will run up hard against 'the pins' of another range at the end. My Autopilot Level mode doesn't work and I crashed a couple of times...
As a weapon, AGM-130 sucks in game because it doesn't emulate either the ballistic curves range variables or the motor 'bounce burn' segment before booster release.
Just that irritating 'bomb whistle' with the motorcase still on underneath.
It also weighs closer to 3K than 2 and it MUST have a centerline datalink if you're gonna do a LOAL (Lock On After Launch) controlled profile.
IOW, Pixel screwed this one up as well.
