I was drunk when I wrote this, I'm not positive that it's true. But anyhow, avoid combined read/write offsets. In a case where you can't burn with EAC on your computer you can still rip with the correct read offset and somebody else who can write with EAC using the correct offset could burn an exact copy from this.

and yeah, I think what you say about the lead out sounds about right to me.

There's also SHNtool cmp mode optional arguments which I haven't tried that I have a feeling might be useful. Has anybody used these before?

cmp mode optional arguments
-s Check to see whether the WAVE data contained in the input files
are identical modulo a byte-shift. Currently, this will only
detect differences up to the first 529200 bytes (equal to 3 sec-
onds of CD-quality data). This can be used to compare WAVE data
within a pre-burned file to WAVE data in the corresponding track
ripped from the burned CD, which is useful if the ripped track
came from a CD burned TAO, and thus might have a 2-second gap of
silence at the beginning. This option can also help identify a
CD burner/CD reader combined read/write offset.

-l List offsets and values of all differing bytes. Output is simi-
lar to 'cmp -l'; in particular, offsets are 1-based. Can be
used with the -s switch.

-f fuzz
Sets the "fuzz factor" for determining whether byte-shifted data
is identical. fuzz is a positive integer that represents the
maximum number of allowable byte mismatches between the two
files in the area searched by the -s option. This allows one to
check for differing bytes between to files that (a) are byte-
shifted and (b) contain at least one error in the area searched
by the -s option. The higher the fuzz factor, the longer the
search takes, so set it low to begin with (8 or so), and
increase it in small steps if needed. NOTE: this switch can
only be used with the -s switch.
