Most people sub-1400 really don't have much of a concept of harass and trading; they just farm and farm until they feel like running off to gank, buy, or something random that doesn't help them much. You can easily use strong mechanics to win trades every time your CD's are up, and freefarm CS while zoning them. I just played a 1v1 against a ~1370 person and was up on CS something like 50-22 when I grabbed my first kill by level 6. I would imagine snowballing in that game would have been easy; grab blues, push lane, and gank constantly.
Basically, some very rough math regarding lane phase would be this:
For every lane you win hard, count that as +1
For every lane that's nearly even, count that as 0
For every lane you feed, count that as -1
Add together your total for 10 games. If you're an even 0, you should have a 50% win ratio, and for every point, add/subtract 5%. If you can't win your lane consistently, then you have some improving to do before you can gain Elo. Before the downvotes come in, let me clarify that this is strictly for lane phase against a single opponent, potentially with ganks included or not (however you want to factor that in).
More accurately would be how well you can do against certain matchups and in-game variables. For example, farming evenly against a hard counter could be considered a win, or only being behind by ~15 CS by 10 minutes while getting camped by their jungler could also be considered a win. In addition, there are millions of decisions you can make regarding ganks, going back, harassing vs farming, stealing their jungle, what route to take while ganking, how well you can organize your team, how mechanically sound your ganks are, etc. The midgame and lategame are also included in your overall skill, so make sure that you're not lacking in any area after you win your lane and you should maintain your fed status throughout the game. Some people have terrible lategames even though they win lane easily, and some people struggle in lane but know how to win the lategame, so weak areas will keep you down and strong areas will boost you up. The fastest way to gain skill/Elo is to improve on your weakest areas first.
Last season I was 1500 rated, and mostly jungled.. I went 12/4 easily. 3 of those losses were due to obvious trolls/noobs. IE - Bot lane Cho'gath Support.. Top lane Nocturne who played like he had never played Nocturne before, etc.
This season, I was 1380 when stats got reset, and I queued up with a friend who was 900 rated last season.
We lost 3 games. This put me in the 1200 bracket.
Most of the games lost seem to be due to lack of direction. In inability to stay together, organized, and compete over objectives. Instead, people tend to roam around a lot more and generally get caught out of position.
They don't understand that when it's 5v4 in your favor ,that you should rush a Dragon, Baron, or steal enemy buffs.
They don't understand that after Baron is up, it should be constantly warded and Bot lane should generally be avoided.. IE - your team should stay near mid/top.
They don't understand who the focus goes to in team fights.
They don't know how to peel.
They chase kills across the map, just to get ambushed and killed by overwhelming forces.
This kind of tactical knowledge is a team wide issue. It doesn't matter if people feed early game or if your team gets fed early game. I can win my lane incredibly hard and still lose thanks to a team who is overall disorganized.
You could argue that this applies to both teams so you should still have 50% win/loss. And sure, it does.. But if you're at 50% win loss at 1200 Elo, you stay at 1200 Elo.
