Yeah this

But it is possible, at low game counts, to get an unfairly high Elo or MMR, or an unfairly low one.

It doesn't take that long (I think it's ~100 ranked games, but I don't know) to balance it, as if you have an unusually low MMR/Elo your wins will stack up quickly, and if you have an unusually high MMR/Elo you will lose a lot.
