No, slower actually. IF you need speed at the cost of yield, high stress events in the last week of veg or first of flower, can get plants to finish a week or two earlier.
It may help plants to finish a few days earlier than they otherwise would have...if you run your entire flower at 11/13.
In my experience, running 11/13 only does a couple things: 1) lower electricity cost, 2) sometimes brings out different expressions of structure, color, terpenes, etc...but again, if you run your entire flower at 11/13.

Lower on time doesn't do much at all. I do 11.5 hours on with all my flower only to save a little electric. Half an hour doesn't do anything to the plants.
My personal opinion, it's just an extra hour of electricity savings.
Flipping to 11/13 as your initial flowering cycle may prompt flowering a wee bit sooner, and my understanding with reducing from 12/12 to 11/13 in late flowering/ripening, it may help facilitate some color change/senescence. I genuinely don't think it speeds up the overall flowering time enough worth mention, maaaaybe one or two days out of a full 12 weeks.
