# Scoring

Currently our rating system works on a scale of 0-100 and is based on time-aggregated data from up to 5 categories: Scar Size, Operating Temperature, Required Power, Maximum Running Load, and Maximum Starting Load.

The equation for all scoring works as follows:

Where:

• P = Points
• i = "Ideal" result
• c = Category
• R = Scalar
• and 100 is the point offset (a maximum of 100 points available)

The 5 categories have a different scalar (R) to determine their scoring curve.

R_c values are:

i_c values are:

Why Pounds per Square Inch (psi) when other measurements are metric? Similarly to Fahrenheit, psi has more convenient scaling for our uses than kg/cm^2 (kilograms per square centimeter). Numbers will be offered in both formats as often as possible.

The final point score is calculated using the following equation:

Where:

• P = Points
• W = Weighting value
• c = Category
• n = Variation number
• t = Total
• a = refers to the category number. SLR-3 having 4 total scoring categories.

## SLR-2

SLR-2 has been replaced by SLR-3.

SLR-2 used 3 categories for scoring: Scar Size, Operating Temperature, and Required Power.

The weighting values for SLR-2 are:

## SLR-3

In SRL-3, the weighting values are:

## SLR-4

In SRL-4, the weighting values are:
