What? He cited a failure rate of 18%, which the article supports and you quote as the "typical" failure rate, taking into account that condoms do break and are used incorrectly at times. If a manufacturer says their manual transmission car gets 45 miles to the gallon, and Fuelly says that same car gets 39 mpg (averaged over a million user mileage submissions), is it intellectually dishonest to use 39 as the working figure when budgeting for gas?
