Um, C2 can be corrected?

Can anyone point me to the section of ECMA 130 that states this?

If not, considering that the "CI" in CIRC stands for "Cross-Interleaved", don't you need a LOT of erroneous adjacent blocks in order to get a C2 error?

In short, does the scratched CD really have a chance of being read correctly simply by re-reading, given that there are lotsa errors to begin with?

edit: spelling and content
