I have never heard of anyone being in a situation where they cannot win/lose more than 3 or 4 LP per game. I have heard of many win streaks that go for 10 - 15 games and get verry little LP per, but then get a HUGE deduction for a single loss. Also, the explaination I have always heard is "All my teammates always feed, I can never get a non-feeding team. I'm stuck in ELO hell!" What you are describing is a totally new definition of that phrase to me.
like i said, their team mates suck, they see it, they cant get around it, it feels like a loss is forced onto them and there isn't anything they can do about it, the match was already decided at champ select.
the scenario you described is when players go on a 30+ loss streak and they're horribly losing, they trash their MMR in the process and they need to rebuild it, they start winning again but they gain very little, they need to win 29 more games in order to equalize their MMR and in turn start gaining an even amount of LP again in either direction.
and the 3 or 4 thing occurs when you are extremely static and you consistently play at that level for a very long time, you start to gain and lose nothing.
