Win a match, and your d1R will never drop because of it. A win can move you up or hold steady — it is never punished.
Losing rating after a win is the fastest way to make people stop trusting a number. So the engine simply doesn't allow it.
Winning & your rating
You won.
Your rating's safe
On dink.one, a win never lowers your d1R.
The short answer
Why a win can look like a loss elsewhere
Most rating systems compare your result to a predicted score. If you were favoured and won by less than the math expected, the formula can nudge you down.
It's mathematically defensible and completely baffling on the court — you won, and your number went the wrong way.
How d1R handles it
Winners are protected
If you win but underperform the prediction, your rating change is held at 0.000 instead of going negative. You keep the win and you keep your rating.
Margins still count
Beat expectations and you climb faster. Winner protection removes the downside of a win without removing the reward for a strong one.
See it in plain English
Every rated match writes a line you can actually read — no black box. Two real examples of what you'll see:
Won but underperformed by 2.1 → rating protected (0.000)
Outperformed by 1.4 → +0.04
The big picture
On dink.one, your rating rewards how you play and protects you when you win. You should never have to explain to a partner why a win cost you points.
Questions?
Can I lose d1R rating by winning a match?
No. A win never lowers your d1R. The engine floors a winner's rating change at zero.
Do blowout wins still help more?
Yes. Margin still matters — beating expectations moves you up faster. Winner protection only removes the downside, never the upside.
What if I win but play badly?
Your rating holds steady at no change for that match. It won't drop, and a future strong result will move you up normally.
Where can I see why my rating changed?
Every match shows a plain-English breakdown of the factors that moved your rating, on the match and in your rating history.
