For each category in the checklist a score is calculated based on the severity of the advices.
If there are any critical items the maximum score is 4, for recommended items it is 6, for optional items 9.5 and for informative items 10.
If there are multiple advices of the same severity (color), then weighted points are subtracted from the maximum score.
The lowest category score determines the overall scan score, which is an indication for the status of your device.
However, it is possible that not all problems and risks have been identified, in which case the score may be misleading.
In exceptional situations, no score is calculated and a question mark is shown.
