I seem to get better average results when I solo que past low Plat, than when I duo Q. Talking over the course of about 300 games last season, I'm as of yet unable to play competitively still this season, due to an ongoing hand injury. Solo queue tends to yield better results UNLESS you have a solid duo queue partner. Duo queue means you have a good chance of ending up with 3 people that don't know kitten they're doing - since duo queue inflates you're combined MMRIs this factual? If it is, it's rather counter intuitive.
