Is this an official player rating?
No. It is a transparent, made-up index that weights goals, assists, key passes and tackles. The weights are our choice for teaching, not an industry standard.

Frequently asked questions
Why normalise to per 90 minutes?
So a substitute who plays 20 minutes can be compared fairly with someone who plays the full match. Per-90 stats are the standard way analysts level the playing field.
Why are goals and assists weighted highest?
Because they most directly affect the scoreline. The weights here (4 for a goal, 3 for an assist) reflect that, but you should treat the exact number as illustrative.
Does this work for defenders?
Partly. It rewards tackles, but a defender's positioning and marking barely show up in basic stats, so the index understates them. Read it alongside the defensive calculator.
How should I use the score?
As a rough, comparable snapshot, not a verdict. It is best for spotting big differences, not splitting hairs between similar players.
