If a min threshold for temperature compensation is not defined by the user, SGP will use a value of 15 % of the AF step increment. In your case, the AF step increment is 800 steps, 15 % of that is 120 steps. So if the calculated correction is less than 120 steps, SGP will skip the correction.
You can set a lower value for the min threshold, see: 353: Temp Comp - Set Min Threshold? .
