I notice you are using sector size of 512B. Is this an NTFS formatted drive?
I have a vague recollection that most NTFS drives have a sector size of 4096B (but might be wrong). I was therefore wondering if it might get a better result with that larger sector size. Don't know enough about drive layout and ddrescue to know if my vague memories are correct, and what implications it would have on the drive. Hopefully someone else will know about this better.

*THIS* is the key! While it possibly slows down the recovery on a
normal drive, in this case it's improved my average read rate to
~200KB/sec and it doesn't degenerate after bad sectors.
