That sure doesn't seem like alot to me, but every little bit helps assuming you don't have sacrifice in other areas such as ride quality or stiffness.
1-2% difference in speed.
0.01 = 3% of 0.33, a typical CdA for an optimized race position, and it takes around a 3% difference in power to yield a 1% difference in speed.
Whether that's a lot or not is up to you. 1% = 6 seconds per 10 minutes.
And I agree: Cervelo integrity is looking very good with this test.
