Issue with custom gauge display -- "n-States"

[OneRound]

I created a "n-state" gauge with 26 steps from 0 to 25.  The gauge is attached to CPU temperature.  I also have a simple sensor set to CPU temperature and that temp reads the same as my motherboard is reporting, so Aida does read the value correctly. 

I set the min-max values of the gauge to 20 and 95.  20 being room temp and 95 as hot as I want to see until I understand my new system.

As I understood it, 95-20 means a 75 degrees range.  And with 25 steps in the 75 degree range each 3 degrees change should move the gauge one more step on the display.

So, with a temp of 40 degrees, I assumed I would get either 6 or 7 steps out of the 25 displayed on the gauge.  But I'm getting about 14.  I will include a screen snip below.

Hopefully someone can give me some insight into this issue.
