True?
You are stretching my 737 knowledge! I have never read or heard anything definitive about whether or not horizontal tail control (either electric or manual via the trim wheel) would be stalled out if the elevator were at blowdown and thus generating maximum force on the jack screw. I would hope that someone on this forum with that knowledge would share it with the rest of us. Not wanting anyone to find out the hard way my recommendation is to keep up with the pitch trim so that the column forces don't build up to the point where you become the one to find out in flight.
