Direct Fire Weapon Accuracy

[Jubala]

Does different DFW's have different base accuracy values or does all weapons have the same base accuray which is them modified by target size and sensors/ecm?

This is interesting because if you look at the Anti-Proton Beam and the Meson BLaster the APB does more and more damage the closer you get while the MB does the same damage at all distances. However, both weapons have the same chance to hit at the same distances and this chance get's higher the closer you are. So why use MB at optimal range with poor chance to hit while you can use APB's at point blank range and have a higher chance to hit and do more damage when you do?
