If I am in a 1v1 battle with someone in Star Wars Battlefront, I usually hold own the right trigger. If I pressed and released frequently instead of holding my finger down, would that increase the efficiency?
It really depends on your weapon. If you have a rapid fire blaster like a pistol, it would make sense to hold down R2 (but only until your gun is near overheating). For guns like the shock blaster and ranged weapons, intermittent fire is probably best - in the former case, you'll use up your limited ammo too quickly, and for longer range, heavy guns, you want to be able to adjust your line of fire to track distant moving targets more easily.
