I too have observed this same behavior of the read of good sectors being
slow after encountering errors, and stopping and restarting resumes at a
good read speed again. I will make a note to check for sure in the
future, but I am pretty sure it happens with direct disc mode also.

I do not remember to have observed this behaviour, but my drives are
far slower than the ones you seem to be using. If you are missing
something, then I am also missing it. :-)
This behaviour has been seen on multiple versions of ddrescue and
multiple different drives and systems. Am I missing something obvious?
Maybe it is some internal switch of caching modes. Does this also
happen with direct disc mode (option -d)?
