We have been doing that in the past for Nova, with little success. The
reason why "reviewday" is called "reviewday" is because... well... there
were review days.
The wiki page was a bit eaten by the wiki conversion, but you can still
read it at:
In the end, a strict rotation didn't work out because people just didn't
review on their review day, but rather when they have one hour free
waiting for a patch to pass gate or whatever. In the end, the rotation
gave us way worse results than random ad-hoc reviewing, because people
would stop reviewing on days other than their review day, and would
regularly skip their review day altogether.
Furthermore, there is some specialization going on: I prefer the two Xen
experts in nova-core to review one hour every two days rather than one
day every two weeks... because then Xen patches get better review
So I'm not convinced *at all* that a reboot of this would yield better
