Accuracy

The share of your decisions graded Best or Correct.

Last updated

What it means
Accuracy counts a decision as correct when its grade is Best or Correct, and wrong otherwise.
How it is calculated
Accuracy = decisions graded Best or Correct ÷ all decisions.
Worked example
180 passing grades out of 200 decisions is 90% accuracy. If 120 of those decisions were easy folds, accuracy on the other 80 might be much lower.
Why it matters
Accuracy is easy to read but flattering, because trivial folds inflate it. EV loss is the better headline.
