Performance estimation
Reference: ISO 13528:2015 Statistical methods for use in proficiency testing by interlaboratory comparison
MitoPedia concepts: "MitoFit Quality Control System" is not in the list (MiP concept, Respiratory state, Respiratory control ratio, SUIT concept, SUIT protocol, SUIT A, SUIT B, SUIT C, SUIT state, Recommended, ...) of allowed values for the "MitoPedia concept" property. MitoFit Quality Control System"MitoFit Quality Control System" is not in the list (Enzyme, Medium, Inhibitor, Substrate and metabolite, Uncoupler, Sample preparation, Permeabilization agent, EAGLE, MitoGlobal Organizations, MitoGlobal Centres, ...) of allowed values for the "MitoPedia topic" property.

- Accuracy: It is defined as the closeness of the results to the true value. We can quantify the accuracy by assessing systematic and random effects on the results.
- Precision: Is the closeness of the results between them not to the true value itself. The two most common precision measurements are the Repeatability and the Reproducibility
