Okay,we agree that the table refers to T/O at r/w limited weights.That much is clear.
Therefore shouldn't the higher weight t/o have a greater V1 adjustment(due to inertia,..)compared to a lower weight t/o?
The fact that the lower weight t/o is assumed to be fm a shorter r/w shouldn't be a factor as they are both r/w limited.(Re:your earlier post)
P.S Are you saying they encouraged rotating before Vr?(Vr-10 probably would be below V1 on balanced field t/o.)
