I am creating this topic because I was surprised when re-reading Accuracy that it states there was no linear correlation between Card Accuracy and Spread.
So I did some quick research.
My results showed there is 0-deviation linear correlation.
In the below formula, "12" and "0.12" are both EXACT VALUES.
Spread = 12 − 0.12 × Accuracy
Accuracy = (12 − Spread) / 0.12
It is interesting to note that the formula is accurate, even on the extreme ends of the scale.
- First table is data was gathered using gearcalc.
- Second table is Accuracy/Spread both recalculated from the base Spread/Accuracy
- Third table is the difference (percentage based) between the original value, and the calculated value.
The error is given as "difference"/"value" where:
- value is the spread for spread calculations
- value is "100-Accuracy" for accuracy calculations
In the above table, most "error" are below or around the 0.1% threshold.
Regarding high accuracy weapons, there are a few "freak" occurrences of high deviation, going up to 5%. However, at these scales, the input data accuracy (the difference between 0.16 - 0.17, or 98.6 and 98.5) is actually higher than 5%.
In all cases, the deviation is smaller or equal to the input data precision => Deviation can be considered null, or "visibly null"
