With Plasma I practice the one-two punch and am always happy with the results. The first volley may get depleted down to nothing but the second rolls in and eviscerates the target.
Also try to maneuver so that you have more than one possible target, with the Plasma R ships I generally shoot between 8-12 inches and take the e-Bleed penalty for strategic reasons. If the enemy rolls a bunch of IDF's in the movement phase I may switch targets to one of those ships that passed its IDF roll instead of the initial target in the attack phase, (who may have been a feint anyway) leaving one less ship to give IDF.
Also if the enemy is picking IDF as their SA they are not choosing a SA that is endangering your ships and that much less phaser is headed your way.
