How do you maintain your rank?

The point swings are crazy. Sometimes you can't lose. When you start to get runs of bad luck, they come in seemingly neverending waves.
I was riding a new personal best until a couple days ago. I have had some really bad dice and drops, and I'm pretty much guaranteed to have 2 pair while my opponent gets a 3 card cash at the critical point in a standard game. I've dropped 300 points in the last 2 days, and still falling, as there are several games I'm eliminated in that haven't yet ended.
I assume this happens to everyone else too. How do the more established players maintain their rank? Do they play mostly team games? Or not play very many games at all? Or do I just have bad luck?
