Yes I did the no wiper/ cowl fillet thing for quite a while. All it demonstrated to me was that my testing wasn't good enough to pick up a change that small, if in fact there was any change. It also demonstrated that getting caught in the rain or getting splashed on with no wipers is a greater inconvenience than the .0000000000001 mpg gain.
