Beets temp variance math is wrong

trying to find a good spot to grow beets, 12.5 desired temp and 45% moisture.
Found a spot with 12.0 temp and 41% moisture, only yields 1 beet, and says temp match is at 73%,
Isn't 12.0 96% of 12.5 ?? So what is it I am missing that makes the math off on this ?

Yea the math works a bit difrent i dont know the exact numbers but im gonna give a fictional example of how the math works.
Lets say for example these Beet's grow at 12,5 degrease desired, and the beet are 100% then.
and the beets have 0% desired temprature when there's more then 2 degrease difrence so it would be 0% at,
more then 14,5 and less then 10,5.I think it works like this, keep in mind i took the 10.5 abd 14,5 as fictional numbers for the actual numbers we need to test ingame.
then this would be the result if there is no curve in the math,
10.5  0%
11.0  25%
11.5  50%
12.0  75%
12.3  90%
12.5  100%
12.7  90%
13.0  75%
13.5  50%
14.0  25%
14.5  0%Hope this makes sense,

Ok i became intrested and took some actual measurment from in game this time to get some numbers straight. here is a litle somthing i gathered.
Beets  12 Desired
14.8 = 41%
14.1 = 4%
13.9 = 3%
13.4 = 28%
13.3 = 35%
13.2 = 38%
12.6 = 68%
12.2 = 92%
12.0 = 100%
11.4 = 68%So i took a lot of difrent temprature samples by planting beets,
and what we can see its not a steady increase/decrease,
so get a 100% clear picture we would need a measure points at every 0.1 temprature difrence.but let me create a simple line graph to give you a id with the data i colected a perfect graph
would have a smooth curving line.

Excellent work, thank you. This answers a lot of my questions.
