OPR · Open Player Rating

Ratings & Levels, Explained

Where your number starts — and how it moves.

“Your rating is your reputation —
and every match either backs it up or dents it.”

Part one

1 · The starting scale

Every player begins with an initial rating — a starting point on OPR's scale, set once when they join. The working ranges:

InexperiencedImprovingSolid club playerStrong / advanced
Men1000–12001200–14001400–16001600–1800
Ladies900–10501050–12001200–13501350–1500

2 · The simple route — one default for everyone

Don't want to grade every member on day one? Use the suggested defaults:

Men
1500
Ladies
1300

Start everyone there and simply let them play. This is how most clubs begin.

Why this works: OPR recalculates ratings with every match — and it scores how you played (set margins and games), not just whether you won. A player who starts too high loses rating quickly to those beating them; a player who starts too low climbs just as fast. Within a handful of matches the numbers separate and settle around each player's true level — the starting point simply stops mattering.

3 · The bespoke route — grade your own players

If your club knows its players, you can set each member's initial rating individually using the ranges in the table above — your coach or committee simply places each player in a band. OPR's bulk member upload takes a per-player starting rating, so a graded list from a spreadsheet loads in one go. Bespoke starting ratings mean the very first ladder already looks sensible; the engine then fine-tunes from there.

Either way, you can't get it “wrong.” Initial ratings are a starting point, not a verdict — the match engine does the real grading, match after match.

4 · From rating to Level

OPR shows each player and pair a Level — simply the rating divided by 200. It's the friendly headline number used across ladders and tournaments:

Part two · How your number moves

5 · Four things decide how much it moves

1

Who you played

Beat someone the club expects you to beat, and you barely move — you did what everyone knew you'd do. Beat someone stronger than you, and you jump. That's news.

2

How convincingly

Squeaking through 7–5 in a decider says “it was tight.” Winning 6–1, 6–2 says “you were clearly better.” The system watches the games, not just who won.

3

How much you played

A three-set battle carries more weight than a quick two-setter — there's simply more evidence in it. One set counts least, three sets most.

4

How close it was to expected

If you were the underdog and pushed a stronger team all the way, your loss is cushioned — you did better than anyone expected. Lose the way you were supposed to, and it counts in full. A brave loss never costs as much as a thrashing.

6 · Close losses are softened

Before every match the system already expects a result — it knows the gap between the teams. When the favourite wins by less than expected (the underdog kept the games close), the losing team's drop slides down — the tighter the games, the smaller the penalty. It's measured in games, across however many sets you played.

Here's a stronger pair (expected to take about 75% of games) winning three different ways — and what the losing team drops:

Result (favourite wins)GamesHow closeLoss
6/2 6/3 6/218–7as expected−16.6
6/4 6/4 7/519–13closer than expected−7.1
7/6 5/7 7/519–18nail-biter−1.8

Same winner, same result on paper — but the closer the games, the gentler the drop. Nothing here rewards losing; a loss only ever hurts less.

7 · The questions everyone asks

“Why did my partner and I move differently? We played the same match!”

Because you didn't play the same story. Your ratings were different going in, so the club expected different things from each of you. If you were the underdog and won, you gained more — you had more to prove, and you proved it. If your partner was already the favourite, they gained less: winning was expected of them.

“Why am I still behind someone who keeps losing?”

Because they started from a higher reputation. Losing brings them down, but a reputation built over 40 matches doesn't collapse in three. Keep winning and you will pass them — the system just won't hand it to you overnight. That's the whole point: it's slow to be fooled, in both directions.

“Does a close loss ever earn me points?”

No — a loss is always a loss. Keeping it close against a stronger team just means it hurts less. You only ever climb by winning.

“I won in straight sets but only just — why did I gain less?”

The system watches games, not only sets. If you were expected to win comfortably and the games stayed tight, you didn't quite meet expectation, so the swing is smaller. Win more convincingly and you'll get the full gain.

“Someone has played more and won more sets than me — why is their rating lower?”

Wins are counted, but they aren't all weighed the same. A pile of wins against weaker pairs moves you less than a handful against strong ones. Open their profile in the app and look at who they actually played — the answer is usually right there in the match list.

If you remember one thing

“Beat who you're supposed to beat, you tick along.
Beat someone you shouldn't, you jump.
Push a stronger team close, your loss is cushioned.
Get thrashed by someone weaker, you drop.
The rating just keeps an honest record of what actually happened.”

8 · Comparing with Playtomic (and similar apps)

Many players already know their Playtomic level and want to know where they sit on OPR. The two systems measure differently — OPR's scale is wider and doubles-first — but as a practical rule of thumb:

OPR Level ≈ Playtomic level + 5.5 to 6

So a Playtomic 4.0 typically sits around OPR Level 9.5–10, and an OPR Level 7.5 player is broadly a Playtomic 1.5–2. It's a guide, not a conversion — no two rating systems map exactly — but it gives your members an immediate feel for their number. OPR works happily alongside Playtomic: book your courts there, and let OPR run your club's own ratings, ladders and tournaments.
