The underlying problem is that the rate is repainted several times a second,
using a numeric filter to approximate the ETA value.  My original
implementation of ETA limited refreshes to once per second, but LP's
alternative was deemed better by the majority of the people on lynx-dev.  That
was a few years ago.
