Am in SP and finished missions. Wound up in one of the Tau systems that has a asteroid field rich in Niobium. Was getting lousy yields for the effort. Turned off all guns but my turret. Return rate went up to about 90% per rock blasted. Seems that all those L10 guns coupled with different projectile velocities was causing the metal to come out of the rock and then get blasted by the slower projectile..... Duhhhh.

So, turn off engines, turret/mouse mode [H & Space bar, leave on only your turret and fill your hold. As there would be a panicky moment bringing the other weapons online should you get attacked, it would be best to do this when neutral or better.

Cheers,
