Unity ranking buffs

Good evening,
I hope this is the right section for this matter.
I have a question regarding the additional buffs on the Unity NMs items, that depend on the current rank of your chosen Unity trust.
I'm trying to understand, without the need to change Unity trust and test it myself, if the lowest Unity ranking additional stat on these items applies when the Unity trust I chose is anywhere on the list?
For istance I had an eye for Nourishing Earring +1, which has a buff marked as 'Unity ranking: "Cure" potency +3~4%'. As written the lowest buff you can get off this is "Cure" potency +3%. My question is does this lowest buff possible apply even if my Unity trust appear last on the Unity ranking list? So to be considered as a fixed buff?
Ahead in time, thank you very much for your enlightening response.

Yes, when it says 3~4 that means every unity except first place gets 3. Even in last place you still get 3%
