Would be a bit interesting, because I had an alt account for a bit. And just a few games into quick play I was playing with people around high diamond.
But here, the system isn’t getting any data at all. Though the system is very quick, and in your 5 games of placement it will probably put you around where you should be.
Their experiment suggested that QP MMR is entirely ignored when placing new accounts in comp. Having the default QP MMR wouldn’t make a difference.
Unless they’ve changed how it works, it’ll seed him in mid-high gold and the first several games will have increased SR gains/losses, so he’ll be able to climb pretty quickly just from winning games on a new account.
I also once did an experiment. I refused to believe I belong in gold, so I just made a new account and now I’ve maintained mid high plat on it for ages and I even hit diamond, but I still struggle to get out of high gold on my first-ever account.
Not necessarily. The person I’m citing found that they were experiencing larger changes in SR “until game 18 or so”. If the exaggerated changes extended beyond 10 placement games, they can certainly extend beyond 5.
