Hi,
Sitting in the center seat it is entirely possible to move sideways slightly and observe the trim position. Other considerations in reading the trim setting would be turbulence, the fact that the indication and pointer are on the top of the indicator and one is viewing from the rear, (there is no parallax however).
Well .. as the THS was in full deflection .. honestly .. regarding any error of interpretation .. we can put the eventual parallax out of the game.
I assume if one check the pointer of the THS wheel .. it will see immediately that the pointer indicate a full deflection ....
