So the difference must be larger than 6%.

It depends on what you are measuring. Prior to about 2006 it was believed that most mutations were changes in single nucleotides (called SNPs). Measuring the frequency of SNPs with available sequences showed about a 0.1% difference between human individuals and about a 1-4% difference between humans and chimps.

It was then found that about 10% of the human genome can vary in copy number (CNV). These are sequences, sometimes genes, that are present in multiple and variable numbers of copies. CNV differences occur at a much higher frequency than SNPs, about 10-fold higher. There are other forms of variation as well involving structural rearrangements of the chromosome. If we take these all into account the genetic difference between any two randomly selected humans will be about 2%. The creationist arguments take all these variations into account and find differences between human and chimps at about 15%.

So there you have it. If one looks only at SNPs, a chimp is about 10-fold different from you than another unrelated human. If you look at SNPs plus CNVs, a chimp is still about 10-fold different from you than another unrelated human.

Much ado about nothing.
