Adjusted save percentage
Meaning
Evaluation of the goalkeeper performance by considering the difficulity of the saves made and standardization of the shots faced.
Calculation
For several shot types and positions Expected Saves are calculated. For each of these the difference between the actual saves and Expected Saves is calculated in percent. This percentage is weighted by the share each of these has on average and the result of that is then multiplied by the average save percentage to have a number that resembles a save percentage.
Interpretation
More meaningful goalkeeping statistic than just the number of saves or save percentage. Easy to interpret as the interpretation is the same as for the „normal“ save percentage, where the average is about 28 per cent and the higher the percentage, the better was the goalkeeper.
