This is because of you entered % as unit. Athom multiplies the number by 100 to show the status indicator as a percentage.
(Internal dimming values, for example, often go from 0 to 1).
So either use another unit (f.i. use pct instead of %)
Or divide the number by 100 in the calculations.
In your case, omit the *100 part
