I don't really experience swings like that, but one thing I have noticed is that some I tend to hover around 55, most of my opponents agree in the mid 40s, meaning I win a lot of games but my level doesn't change. I've checked many times and my search settings are default, so I don't know what's causing this. I also don't know why I'm rambling on about this in this thread; it's late and I'm tired.
