This can help people playing through harder difficulties in many games if it works and can for sure help anyone wanting to just get an achievement over with or having to earn one again from swapping to another gaming platform.

Another plus is saving on painkillers for parts you know might be a bit difficult.

This just means that instead of taking cover and popping out to shoot at someone. You instead are aiming at the enemy still, but just straight up standing and shooting through any cover. Crouching can work but be careful since walking can pop your head up. Laying down can help especially on the yacht in the open with enemies across.

Person targeted is on the right with the default white / red reticle.

So far this has helped in the laser hallway, going through parts of the favela, the open yact section, C4 visits, and shooting range which were places with most enemies that I can recall. It can also help fighting the police office lmg guy with no bullet time and meds if you find the right spot.

There'll be enough pain pills to snipe recover the roof lmg guy 3 times easily and be stocked only worrying about Becker's grenades.

Obviously knowing enemy locations can help pretty well, but just remember to use this tactic for certain situations if you don't want to ruin your fun in the future.

Hopefully this helps anyone that doesn't know it already.
