I am evaluating dbpoweramp ripper+converter and I was wondering how accurate the AccurateRip really is ?

According to the AccurateRip information on this site

https://wiki.hydrogenaud.io/index.php?title=AccurateRip

"An optimization oversight in the original AccurateRip checksum algorithm results in an unintended loss of accuracy: about 3% of the audio data is not counted in the checksum at all. The left channel's samples are fully included, but in a 65,536-sample cycle, half of the right-channel samples are treated as if they're missing anywhere from 1 bit to all 16 bits."

And this discussion

AccurateRip check sum calculation has a serious flaw that means that errors can go through without AccurateRip noticing it ? It seems like the accuracy is around 97%. And what about ignoring the 5 blocks from the beginning and end of a track ? What if there are errors ? Not detected ?

Should I enable C2 error detection ? According to this site

C2 error detection accuracy is 99.9 %, is it better to use secure C2 mode ?
