Spot-on,
@TiGeo !
For the record, I´ve seen times where they pointed out low TBN and suggested the OCI at least stay the same, and IIRC, a couple of times where they said to shorten it a little. But again, maintenance nerds are indeed the only ones using BS outside of fleet managers. And fleet managers don´t usually post here because they get their fill of it with their jobs.
