Regardless, I think the important thing is to save gas and increase your mileage. Just because you're an expert doesn't mean you're a better hypermiler than one that is skilled or one without any title. Some people aren't doing all the methods either because it could damage the car or simply because they aren't comfortable with it and that's fine. Maybe your commute has tons of hills or it's completely flat. No one here thinks less of anyone (or they shouldn't...) just because you're not an expert or your percentages are lower. Just my two cents.
