New description:

 See attached files.  Relay powerlay lowered max advertised bandwidth late
 5/23.  SBWS longclaw never recognized the change.  SBWS bastet saw the
 value but was started after the change.  Torflow recognized the change
 instantly.

 ~~ Have observed that SBWS, when it makes note of max advertised
 bandwidth, averages the value.  This value should not be averaged, the
 current value whatever it is apples. ~~
