FAQ
1) What does the adjusted save percentage represent?
It estimates a goalie’s performance after accounting for shot quality. The calculator blends a traditional save rate with an expected rate derived from xGA, then adds influence from high‑danger splits.
2) Where do I get xGA?
Use any shot‑quality or expected‑goals model you trust. Many models weight factors like shot type, distance, pre‑shot movement, and rebounds.
3) What range should the weighting slider use?
0 relies entirely on traditional save percentage, 1 relies entirely on the expected save percentage. A middle value lets you balance observed results with model estimates.
4) How is high‑danger influence applied?
High‑danger SV% is blended in proportion to its shot share, capped at 50% influence to avoid overdominance in small samples.
5) What is GSAx?
Goals Saved Above Expected equals xGA minus GA. Positive values suggest the goalie stopped more than expected given shot quality; negative values suggest fewer.
6) Why can my adjusted value be below the traditional value?
If the expected rate is lower (tough shots) or high‑danger results are poor, the blend can reduce the overall percentage, reflecting context.
7) Can I benchmark across leagues or seasons?
Yes. Update the league reference save rate and keep the same weighting strategy for an apples‑to‑apples view across different environments.
