Thing is, there have been other studies that showed that the Lazer vent cover yielded almost no improvement over the base helmet. I think there is so much margin for error that Taren's results are effectively meaningless/non-repeatable.
Head and helmet positioning, and then how the helmet fits into the contours of your body profile while in the aero position, probably has a bigger impact on outcomes, than helmet to helmet design.
Gerard Vroomen - Co-Founder of Cervelo ounce told me, that sometime things and set ups that LOOK aero, ounce set up and on the bike with the rider on the bike, don't always end up being that aero! It's the whole package that matters!
