I ripped some albums with EAC and Accuraterip. Generally I was getting good results from Accuraterip.
For some reason I then decided to check the cue/wav image by loading it into Daemon Tools and running a test and copy image. I have checked a few albums and the results are not consistent.
Here is the log from one album

End of status report
From the original rip the CRC of 76F34DE3 is correct.
Why does the test result give me this correct result and then the actual copy gives me something else and then tells me the tracks are not ripped with confidence. All was fine with the original rip.
