The implication of calibrating the sub 10dB higher for a given input suggests that:

1) When a sub is used to output re-directed bass from the other channels (e.g. mono sub with 80Hz crossover from the other speakers), this redirected bass must be reduced by 10dB or it will come out too loud.

2) Cinema does nothing. Discrete lowers the LFE channel by 10dB.
