Not much. I was surprised that the effect was as large as it is, but for the standard recreational rider it's not much.
On the other hand, for a racer who has no beer belly to loose, and who has purchased, at hideously high prices, the lightest widgets there are, and who has already drilled out their chainrings and other metal items, it might be worth carrying the Helium tank in the team car.
