I certainly agree with you said here... except going form 1% to 2% failures is a 100% increase in failure rate. But you know that,and this isn't what you really meant, so I'll shut up now.
Tom amused by really small and really large numbers Dalton
Does the phrase "not statistically significant" ring any bells here?

FWIW, the Big Three automakers measure their warranty costs in dollars spent per vehicle sold. Some years ago, that number at Generous Motors was approaching $800 per light-duty truck - about four percent of the average dealer price.... It's tough to separate the signal from the noise until you get enough frequency of the same thing happening to form a clear picture.
