Good point.
The trim sheet has: Indexes, MACs, and Units. The FCOM has Units. Nowhere that I can see mentions trim degrees. If Boeing is quoting real degrees here, and not trim units, then that is a whole different ballgame. What is the conversion between degrees and units?
However, if the aircraft was slow, nearing the stall, you would indeed need 2.5 units (or degrees?) of forward trim. The problem being that you definitely don’t want 2.5 units (degrees?) when doing 250 kt...
