I quit updating my Earthquake Dart Board back in early March of this
year. The project lasted for just over 16 months with impressive
results.

Magnitude range: 4.00 - 10.00
Distance range: 0 - 1000 kilometers
Predictions: 5489 (total number of predictions made so far)
Prediction Hits: 3688 (number of predictions with at least one hit)
Total candidates: 18952 (total number of quakes within the magnitude
range)
Total hits: 17450 (number of candidate quakes within range of a
prediction)
Candidates missed: 1502 (number of candidate quakes missed)
Hit/Candidate Ratio: 92.075%
Hit/Prediction Ratio: 67.189% (predictions with hits vs total predictions)

To put it simply, 67% of my predictions successfully predicted
92% of the worlds earthquakes of magnitude 4.5 or above.
