Hmm - it doesn't sound to me like they vary much at all if that's true.
If those rates are per bit, 10^{-11} would be something like one single
bit error every 10 discs, which is more than good enough. Bear in mind
that single bit errors will be totally inaudible.
My two drives are a Pioneer DVD-ROM and a Lite-On CD-RW. 1 error every
10 discs might be about right, for new discs - it's hard to tell at that
level, since probably more than 1 in 10 of the discs I rip are old and
scratched enough to cause problems.
