It does feel a bit short; prior results can sometimes be interesting for
comparison purposes, although even that value diminishes quickly over
time.  Is there a strong reason to favor 8 weeks vs. say 26 weeks
(i.e. our development cycle length)?

Bryce

I would also recommend a longer period, at least 12 or 16 weeks. The selfish reasoning is that this would give us at least 2 kernel SRU cycles worth of (hopefully) passing logs to use when triaging a failure.
