Comment(by arma):

 Replying to [comment:6 mikeperry]:
 > However, personally, I think that in reality clients are rotating off of
 their guards much quicker than even the 1.5mo limit. At least, it feels
 like my Tor clients were doing that when watching path bias counts.. I
 think this might be the same problem you describe when talking about the
 age of the median byte of the Guard flag (Guards may actually already
 going up and down/losing their flags way faster than our limits). For this
 reason, I'm wondering if simply changing the rotation period to 9.5mos
 might not actually change the rotation rate in practice.

 See Figures 4 and 5 in the COGS paper. At least during the time period of
 that Tor network dataset in 2011, voluntary rotation was a much bigger
 risk component than natural churn.
