Seems like ideal improvement range is level 4. If we assume this bonus damage requires integer, for dual guns the next damage increase would be at levels 6&7 (requires 1 extra gun to be destroyed) for 5 bonus damage.

For dual guns the fastest way to improve damage to round up to next level is at levels 1&1, 2&3, 4&4, 6&7, 9&9.
