Ascended chest pieces give incorrect amount of research notes.

[Adotiln Urthadar.1823]

It's possible this is intended but it seems unlikely. Ascended armour pieces seem to salvage into ~450 research notes each, but chest pieces only ever yield 275. I would guess there is a base amount of notes you get plus a "roll" for more, and chest pieces aren't rolling for the additional notes.

I think it is intended (but i don't know why as IMO it does not make any sense).

• Contains 500 research notes.
• Salvaged from:
  • Crafted ascended armor (1)
  • Crafted ascended weapons (1)

As you can see there are 2 lines saying "excluding coats" and 1 line that is about ascended coats only.

That's just player research though, no? Clearly the specific research items aren't being salvaged from coats but I don't think that implies it's intended.

Yes, afaik that info is from player's research. But if it is not intended, then it would be a bug. I don't think Anet will admit that it is a bug, so it's "intended" 🤪
