What is winfield optimum

I'm currently at level 46, having played 42h. My K/D is a measly 0.46, but it once was 0.1 and it's steadily improving. I always have enough cash to equip my men, so I guess I'm doing well enough.
I’m my experience, while a true aim always helps, what really makes or breaks you in this game is positioning, but I couldn’t find a good overview on the subject. While I don’t feel I’m qualified to do this, I thought I could share my principles on it, and you guys, especially the more experienced ones, could expand on it and/or correct it.
 
Choose your engagements where: -You threaten them from many angles, are threatened from only one. -The range suit you, and not them. -You have cover, and they don’t.
 
You have cover, and they don’t. Having cover helps a lot. Not only makes you a smaller target, but it also provides safety should you need to reload or heal. Many engagements are decided by who can heal more, or in someone taking a shot while reloading.
Height can really help here. Your legs cover some angles on your body which in turn cover some angles on your head when you are above someone, and the opposite happens when you’re bellow. Also if your above usually you have more opportunities to take cover than when you’re bellow. Think of being on the top of a hill, fighting someone bellow. If you need you can go back and the hill will cover you, but they don’t have the same advantage. If you are fighting someone through a window on the same level as them you could just step to the side to take cover, but they can get a luck shot through the walls. If you’re fighting someone from a window above them, if you go back it’s very unlikely that they’ll pull something like this.
 
The range suit you, and not them. Guns are widely different in optimum engagement distance. If you have a fanning chain pistol and a Cadwell Rival and someone gets you with a Sparks from far away you’re toast. If you have a Sparks and a Silent Nagant and someone storms the compound you’re in with a Cadwell and a fanning chain pistol you’re probably gonna end up dead. Know your weapons and know at what distance they perform better.
Also chose your weapons for the distance of your likely engagements. If you have a Winfield Marksman and a sawed-off shotgun, switch to the shotgun when entering a compound, if you find someone by surprise you’re gonna want the best weapon for the distance already in your hand. In the same vein if your running shotgun and Uppercut keep your Uppercut at hand when walking in open areas.
 
You threaten them from many angles, are threatened from only one. Dividing your attention between multiple threats or possible threats makes you really less effective and more error prone. Being attacked from an unexpected direction frequently spells your doom.
If you can, try to have you and your partner threating the enemy from different angles. If you plan on camping or ambushing someone, don’t sit on top of each other. If someone engage your partner but did not see you yet, don’t rush through the same angle, try to go around. Also try to keep your options open regarding attack angles. If your defending a building against another duo, try to shoot through different windows and doors. Keep them guessing about where you’ll turn up next. If you’re in the open, try to use the cover you have to turn up somewhere else to shoot, or flank them if you can. If someone is near a building and you’re having a shoot-out through the door, go outside somewhere else and shoot them from another angle.
Height also really helps here. In a lot of cases, especially in shorter range engagements, the options you have to threat people are also options they could use. But height is something else. If you’re above someone you usually can go down easily by just jumping, but they have pretty limited options to go up. This turns up a lot in buildings, but it also happens in some places in the open.
Also be wary of different angles of attack against you. If you don’t see an enemy where you think he should be, try to check the other possible angles he could have on you.
 
Choose your engagements Don’t just go guns blazing on anyone you see. Also if someone engage you, don’t feel too committed to the fight. Be deliberate on your noise choices, you don’t want to be found if you did not choose to be found.
If you see someone unexpectedly and they didn’t see you, think if that’s an engagement you want. Did he just walked into a building you’re in with a Sparks, and you have a shotgun or saber? You probably want to take him out. But if you’re in open deep water with a short range load out and see someone in the distance near a compound you probably don’t want to engage. They have better cover, better range, and more angles
If you’re ambushed, don’t feel committed. Pulling out is frequently the best option. If the enemy chose the engagement it’s probably a good engagement for them and not for you, and you don’t want it. Instead of trying to return fire usually focusing on finding cover is the first priority. After that consider your options.
Sometimes your lot it’s not so bad. You saw where they are, you found good cover, they are on your preferred range. You feel it is a fight you can win.
Sometimes things are not that easy. You either are not sure where one or both of them are, or you are at a bad range, did not find good cover. Usually when that’s the case you should pull out, either to reposition to reengage on better terms or to retreat completely.
If you feel you can reengage on good terms and are feeling confident, you can go for it. If you feel it would be too difficult to reengage on good terms, or are low on ammo/health, just retreat. For example, if someone engage you in a river and you managed to run to the other side, finding cover, the engagement is not so bad anymore if you are in a comfortable range. If you’re not in a comfortable range, maybe there’s a bridge nearby, and you could pull out and go through it to reengage in more favorable terms in closer range. But maybe there’s no bridge, and trying to close the range through the river would be suicide, you should just retreat.
Retreating frequently forces a difficult choice on the enemy: they can go after you, abandoning their good positions, possibly wasting a lot of time and not finding you, or running into an ambush you set up, or they can give up. In the river example crossing the river to chase a retreating enemy would probably open the possibility of being ambushed close range, to the advantage of the retreating hunter. People frequently give up. I managed to get out of a fair amount of bad fights, and let people go because I couldn’t or wouldn’t chase them too. Don’t waste your life in a losing fight, live to die another day.
Also I think these principles lead to some other tips, like don’t walk to close to your partner, as this restricts your options of what angles you can threat your enemies. And gives the enemy that information. The same thing goes for crossing deep water at the same time.
Also try to identify guns by their sounds. Knowing your enemy preferred range is quite useful, so you can engage them exactly at the distance they don’t want to be engaged.
Fire is quite useful to close options. If you don’t know where the enemy are, and they could engage you from too many angles, you can close off some angles with lanterns or molotovs.
Height is useful for a lot of reasons, where you can you should probably engage your enemies from above.
So, what you guys think?
