This is the reason why every score is split between Numerator and Denominator, so that those values can be re-used in the Scoring Formulas of the upper scores.
Calculating a Score Containing Only Questions
Let's use the Scoring Formula to define the values of Score 1.1 and Score 1.2, which contain only questions:
...
The same process would be repeated for Score 2.1 and Score 3, that also only contains questions.
Calculating a Score Containing Multiple Sub-scores
In order to define the value of Score 1, which contains multiple sub-scores, the Numerators and Denominators of each sub-score are used instead of calculating the average of each section:
...
This formula applies even if a sub-score contains more sub-scores, there are no limits for the amount of nested scores.
Calculating the Assessment Score
IMPORTANT: The Assessment Score (also referred to as Global Score) is determined by the score of the Critical Questions in the checklist. If a HNQIS 2.0 Checklist doesn't contain Critical Questions, the score will be determined by the Non-critical Questions.

Calculating the Critical and Non-critical Scores
Previously, a special condition was presented to demonstrate the Assessment Score calculation. This condition was to assume that every question in the assessment was Critical, but in most cases, HNQIS Checklists contain a combination of Critical and Non-critical questions.
