Can someone explain how SR gain and loss actually works now?

For Diamond and above, personal performance doesn’t affect SR

Yes.

@LunarPlains-1344

and everyone gains and loses the same

No. There are other factors besides performance SR, such as recovery from decay, and an SR debuff for very high rated players.

@LunarPlains-1344

The game’s calculated SR determines an overdog and underdog, meaning if your team’s cumulative SR is higher and you lose, you’ll lose significantly more SR and vice-versa. This has nothing to do with your individual SR.

Sort of. The effect is based on predicted win probability, which is not exactly SR. It depends on things like grouping as well (the bigger group gets a bump to its expected win probability).

@LunarPlains-1344

Win and loss streaks are gone.

Yes.

@LunarPlains-1344

The amount you gain and lose per match is determined by the two above systems.

There are other factors. See below.

@LunarPlains-1344

For an unknown number of matches after your placements, you’ll gain more than you usually would to try and get you toward your “real SR”.

It’s about 18 matches (including placements), for a new account. For inactive accounts, this uncertainty in SR comes back. For active accounts, placements only matter about as much as normal games.

Anything else I’m missing?

Yes. I’ve written a more complete explainer (with references) at How Competitive Skill Rating Works (Season 10)

I’m incredibly confused and disheartened after only coming up 40 sr positive after a 6-4 record for the day, after hours of play.

The average gain/loss is about 23 or so. So you only got “cheated” out of maybe 6 SR. And that will probably wash out with more games played. To rank up, you primarily either need a higher win percentage, or many more games played.
