Breathing Volumes
The percentages on both Stridor and its Survivor-pendant Iron Will 
are misleading in their interaction with one another, as contrary to the popular perception of percentages, they do not represent actual percentages in the Game code, but rather numeric values that are combined additively.
A good analogy is a volume slider ranging from 0 to 100, which can also go above 100 if necessary.
- Positive values move the volume slider upwards, increasing the volume.
- Negative values move the volume slider downwards, lowering the volume.

Trivia
- The term "Stridor" describes a high-pitched wheezing sound caused by disrupted airflow, which is also what The Nurse suffers from.
