The Perpignan report told us that the A320 THS has an electric pitch-up stop at 11 deg for a maximum THS deflection is 13.5 deg nose up.
For the A330, according to
A33Zab, there is no such electric limitation.
After re-reading
his post, I can see he had already produced a possible reason for which the THS did not reach the max deflection.
But once again, it was the BEA job to develop that stuff ...
