ADR doesn't correlate with ADR from weapons stats

I have an ADR of 155.8 but if I calculate it through the weapons tab, I get 114.5
I understand that utility shouldn’t be counted in there but I doubt I’m doing an average of 40 damage with utility every round, even if I do play Sova, Breach, Brim, etc.
The values that show up in “loadouts” does seem to be accurate though, besides the eco one (How do I have 156.4 ADR with a DD of 35 if I don’t always buy small shield in pistol rounds? that’s like 120 dmg taken in average)
