You *have* to pull up (at 4g) in bomb dyk for an accurate release. The weapon computer predicts bomb spacing by assuming you will be pulling 4g during release. It is the only difference between DYK (spacing is done via pullup at 4g) and Level (spacing is accomplished via 1g level flight and longer delay). Another thing is that you should trigger unsafe only when the aiming dot is exactly on target, as this designates that point on the ground as the center of impact. You should minimize any kind of maneuvers until the pull up cue.
