Comment (by ra):

 Attached is the result of measurements of ~1.6M circuits, sorted by guards
 and compared their CBT and First-RTT values. Only guards that were
 measured at least 2k times each are included. It looks like a distribution
 for First-RTT is more stable then for CBT. Parameters seem to differ
 between guards for both CBT and First-RTT.
