Fixed wing Level trim how it works

[willyfpv]

Good moring y'all
i have a s800 and after a diff ive found someting strange.
th e fw level trim in pid tab under mechanics is set to 4° but in diff "set fw_level_pitch_trim = 3.920"
is because I have enabled autolevel trim? and so is modified by INAV based on the behaviour of the aircraft and it modifies it accordingly?

Auto level trim sets fixed wing level trim in flight. You should use this as a tuning mode on top of a self-levelling mode, such as Angle, Horizon, or Course Hold. It shouldn't be used on its own or all the time.
