Closing your mouth when you ride should pick you up another minute. ;-)

Then I am screwed!!! It doesnt matter how cool of a racing picture there is of me-all my wife ever sees is my with my mouth hanging wide open!! hahaha!! But honestly I have wondered if it causes enough drag to be slower than a good nose breather.

Actually, if done right, you get a "ram-air" effect with an open mouth that actually jams in more air as you go...kinda like the hood scoop on a race car.
At least that's what I keep telling myself... :-)

Luckily, unlike that fixed/rigid port, my intake/exhaust port can be vectored...i.e. intake, mouth forward - exhaust, mouth down :-P

now that you have optimized it, do your forearms point down?

Nice public service announcment (seriously). A 40k TT will make you realize the importance of details. I learned that this summer when I did my first TT. Prior to that, I did not appreciate this.
But "well, as serious as I ever take it" -- right.

Andy,
Are you using the "Chung method" for your testing? If so, can you share how many runs you typically do and their "order" when comparing between two positions?
Thanks.

46:xx 40K on 400w is impressive. What the air density for that graph?
How much for the track frameset? What size?

Do you have an optimized picture as well?
I can't put my finger on it but your "winging it" picture looks uncomfortable for some reason. But yet still looks really optimal as well.

In anticipation of a return to serious competition next year (well, as serious as I ever take it), I've been spending a fair bit of time at our local "natural wind tunnel" with another fellow (
http://www.twowheelblogs.com/centaur-wind-tunnel
). There are still a few more things that I hope to try before the weather gets too cold, but I have to say, I'm pleased with the progress that I've been able to make so far:
The improvements shown were achieved by experimenting with elbow pad height, tires, and helmets...I've previously tested forearm angle and elbow width, so didn't feel the need to revisit those or other issues, e.g., reach (plus I'm constrained by UCI rules, at least with respect to forearm angle and reach).
FWIW, here's a pic from earlier this year when I was just "winging it":
EDIT: BTW, that frameset is now up for sale if anybody needs a track bike...
Wauzer!! That's a nice improvement! You are at an CdA of 0.20m^2!
What were the changes? I found your post about the arm position, what has been changed after that? Is it with the same bike/wheels/bar or did that also change?
You dropped from 0.229+/-0.005 m^2 to approx 0.20 m^2...
Like your and Tom A. posts about decreasing CdA. Very inspirational! I hope to collect some data of myself soon.

So you are playing with us to see who can guess how you improved your position?

5 mm different from on my road bike.
Are they the same on both sides? ;-)

My legs aren't the same length, so why should my crank arms be? ;-)
Is that the excuse you gave JV about the "captain" cranks on your tandem?

In my part of the country, you could also factor in some protein in your nutrition strategy due to insect intake.
