Forum:Accuracy Spread conversion

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.

Formula
In the below formula, "12" and "0.12" are both EXACT VALUES. Spread = 12 &minus; 0.12 &times; Accuracy and Accuracy = (12 &minus; Spread) / 0.12

It is interesting to note that the formula is accurate, even on the extreme ends of the scale.

Input Data

 * 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

Conclusion
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"
