Um, what? How does this look suspicious at all? Apple's testing process is different from CR's. CR changes some defaults to standardize their testing process across machines and Apple sticks to the defaults. They got different results. Apple asks CR to hare their testing process and as a result discovers a bug in Safari that when fixed improves the battery life. CR even admitted that when they used the standard defaults, the battery life was in line with Apple's battery test results. They didn't write results to cheat battery tests, they wrote mostly working software which had a bug that would not normally occur.
