Have you tried ddrescue 1.22 or later? It shows a count of read errors:

GNU ddrescue 1.23-pre2
     ipos:        0 B, non-trimmed:        0 B,  current rate:       1 B/s
     opos:        0 B, non-scraped:        0 B,  average rate:       1 B/s
non-tried:        0 B,  bad-sector:        0 B,    error rate:       0 B/s
  rescued:        1 B,   bad areas:        0,        run time:          0s
pct rescued:  100.00%, read errors:        0,  remaining time:         n/a
                              time since last successful read:         n/a
Finished

You need to use -M in addition to -A:

  -A, --try-again                mark non-trimmed, non-scraped as non-tried
  -M, --retrim                   mark all failed blocks as non-trimmed


Best regards,
Antonio.
