There is no other numeric comparison possible. These 30,000,000 mutations HAD TO HAPPEN for the difference between humans and chimps to exist, regardless of the nonsense you wish to push. That you challenge the numbers shows that you yourself know that it is impossible.
BTW - here are some articles on exactly how the differences in DNA were estimated. They prove you a liar:
Britten compared the sequence of five chimp BACs covering 779 kilobases with the draft human genome sequence. Sequence substitutions account for about 1.4% divergence, but twice as much divergence (3.6%) is contributed by indels. The frequency of indels is less than the frequency of substitutions, but the gaps can be tens of nucleotides long and appear in both human and chimp sequences. Further analysis of the gaps in other genomes may provide useful insights into evolutionary relationships between humans and our closest relatives.
From: The Scientist - How different are we from Chimps
Roy Britten, a biologist at the California Institute of Technology, reported in the current issue of the journal Proceedings of the National Academy of Sciences USA that the large amount of sequencing that has been done in recent years on both the human and chimp genomes - and improvements in the techniques themselves - allow for the issue to be revisited. In the article, he described the method he used, which involved writing a special computer program to compare nearly 780,000 base pairs of the human genome with a similar number from the chimp genome.

Britten based this on a computer program that compared 780,000 of the 3 billion base pairs in the human DNA helix with those of the chimp. He found more mismatches than earlier researchers had, and concluded that at least 3.9 percent of the DNA bases were different. From: CBS News- Chimps & Humans - Vive La Difference
BTW - with the 5% difference that has now been determined that makes it that 150 million mutations were needed to transform humans from chimps - making it five times more impossible than what you yourself considered a refutation of evolution.
