Do you watch R1's as you buy them, or once you have the full set?

I usually watch them as they're released. There are some series that I might wait until I watch them simply because of all the details you need to remember from one volume to the next. I'm doing that for Twelve Kingdoms. They have it broken into arcs that usually span about 3 discs. I should've done that for Rahxephon as well.
