or is the species doing both..? (AO, Det, and FM)
There are many possible molecule types that the boron is part of and unfortunately there is no way of knowing from a VOA / UOA. With 291 PPM of it, it sure is a prominent part of the additive package.

My bet is AW/ EP for the transmission. For what it's worth, you're right, I don't know. I wish I knew
