That's seven weeks for release, possibly longer based upon
extending the beta period, plus one week of release branch being
frozen following a release. 8 * 4 = 32. 52 - 32 = 20. 20 / 4 =
5 weeks between releases now.

Two weeks is tight, but adding two might be overkill. You don't
want to lose momentum or urgency by allowing too much time.

10 * 4 = 40. 52 - 40 = 12. 12 / 4 = 3 weeks between releases
with a four week beta period. I think that justifies releases
thrice per year. That also makes point releases less intrusive
on subsequent release cycles.
