I haven't monitored this sort of thing long enough to form any real opinion about the meaning behind this, but Lucid's Q3 ratio of delivered/produced (61%) is way lower than Rivian (or Tesla).
Looking back, RIVN was at 48% in Q1'22, 101% in Q2'22 and 89% in Q3'22, so perhaps this is just how managing the ramp up of production then logistics/deliveries happens.
The LCID Q3'22 number of deliveries is most similar to RIVN Q1'22.
Either way I benefitted from the push to deliver before the end of Q3 so I'm a happy customer
