I am in agreement that lagers can/are produced in as few, or fewer, days than ales. A typical, average-gravity lager for me is fermented for 5-6 days and then spunded for 3 days to full carbonation, and then into the kegerator it goes. There is certainly some sedimenting time after this, but is generally to the hazy phase after about 2 days. Lagering (i.e. cold aging) takes place while the keg is tapped, and while there is definitely some improvement in the first week (i.e. melding of flavors and dropping of flavor-containing compounds), after that it's minimal. While I also include low oxygen brewing processes in every beer I make, it shouldn't make a difference for the timeline if it's low oxy or not.
Ales for me ferment ~7 days, then are keg primed for ~10days, and then into the kegerator they go. After that, there's still the same sedimenting and melding phase time.
