Looking at the photo I would say lower your stack, and extend your stem and set your saddle further back ie get lower. Bear in mind all this may (in the short term) make you slower as you will find it uncomfortable hence the need to train in the position. Ideally you need to have a flat back. My rule of thmb is that the "beak" of the aero helmet is resting on my spine and I am unable to see my computer because my head is looking straight ahead.
Dare I say it you may need to think about a new frame - go for a longer frame/top tube, actually go to a good TT orientated shop to try different frames (avoid bike fit!!). Yes looking at the poto again too much air is being caught by your torso. Get Lower
As for the go shorter from Conehead, thats' why I think a longer frme is needed it will allow a flat back, and the shorter stem then will stop the artificial aero position ie get the legs over the bb as opposed to in front of the bb. Explained badly!!
Also your foot/pedal needs to be at the 7 o clock position on this side shown or 5 o clock on the chainring side.... This is the furthest postion that your foot is going to be away from your saddle.
Saying that though, the above comments are correct, for short distances more aero is needed ie less torso showing to the wind.... Long course it doesn't matter so much about aero its more for comfort with being aero only a little bit.
I would get a bike fit done at the a proper shop. That way they can adjust stuff like saddle position, stem length, adjust the aero bars etc.

As I alluded to earlier I ended up buying a new frame - a Cervelo P3C - (as a 40th birthday gift to myself) as this gave me the best compromise between aero and comfort. I used the new set up for all my long distance training and racing and it was /is amazing I now also use it for TT's.
Also my aero engineering mate is a huge proponent of aero helmets, overshoes and skinsuits (ps remove all watches and jewellry)
The best help I got was from my engineering mate who understood aerodynamics, cycling, and the different distance disciplines in triathlon. I accept what you write about position its an unanswerable question as kit evolves and as top riders try new positions.
However I firmly believe in the dilemma of experiment with position and then train in the position.
One reason why I harp on with this thread is that I'm currently experimenting with position. I think I can be 1 minute faster in 10 mile TT's but it will entail a new position, but will this compromise my good tri-distance position?

...Just to confuse things a bit more, here is a more natural photograph - i.e. Brind Surch in full racing flow - not posed. Not quite the best angle, but quite useful...

@brind surch: You've plastered yourself all over the internet. This is the 21st Century. Relax and get over it. I thought it was a good photo though, and did a better job of showing your position.
