To accompany my review of Digital Innovations' SkipDr. AutoMAX in Eli's Review: CD Repair and Cleaning Kits, The Digital Innovations Lineup thread (post #12). Only the last four tracks of the CD-R were scanned as that was where the worst scratches resided.

Before repair:
CODE
        Avg/Sec  Max/Sec    Total              
C1          9.2     99.0  40059.0              
C2          6.2    315.0  27261.0              
CU          0.1     97.0    407.0


After repair:
CODE
         Avg/Sec  Max/Sec   Total              
C1          9.5     86.0  41434.0              
C2          7.8    328.0  34361.0              
CU          0.0      0.0      0.0


Scanned with PlexTools Pro v2.28 on a Plextor Premium.

What the graphs and numbers mean:
C1 indicate BLER - the number of E11+E21+E31 per second (green)
C2 indicate the number of E22/sec (blue)
CU indicate the number of E32/sec (red)
RedBook (the Audio CD standard) allows up to 220 C1/sec and IIRC, about 1 C2 per hour. Presence of even one CU indicates that the data stored in the affected area may be unreadable. As you can see, the repair totally eliminated CUs and made possible error-free extraction in EAC in Burst mode.
