ALF,
I haven't had any problems with the new bombing system. The key to accurate bombing, for me at any rate, is to make a long speed calculation. Although holding the "Y" key while you do the ground track for 2 seconds will get you a green light to bomb, the calibration will be much more accurate if you tilt the sight forward and then track for 30 seconds. Or more.
All of my buff missions are above the wind layer at 14k, and I get consistantly accurate drops. My drops are usually made at 90% throttle, delay 0.6, 500 lbers, from an altitude above the target from 12,000 to 15,000 ft.
My biggest problem is getting lined up early enough to let my speed stabilize and do a long calibration.
Good luck!
