Note that at reasonable speeds, most energy is spent defeating air resistance, which increases quadratically with velocity. In other words, a 30% energy benefit translates to a speed benefit of 14% (sqrt{1.3}-1), a 35% energy benefit translates to a speed benefit of 16%. This is in line with the numbers being reported (even though this doesn't take into account the psychological benefit).
