I'm grateful for the photo of the racer with the high-position levers above. I put mine up pretty high, too (these are Cane Creek brake levers, but they have the exact same shape as Campy Ergo brifters):
I am probably going to try them a little higher even. The problem is that as you move the levers around, the distance to the brake lever from the drops changes. Depending on the curvatures, it might get bigger or smaller as you move them around. I suspect that if I move mine up, the distance will increase. I need to experiment a little more until I get it right, and I suggest you do the same.
After trying a new position, try riding around (or on a stationary trainer) without putting the tape on to save you the trouble of taking the tape on and off over and over again. You don't want to have them in a bad position but find yourself reluctant to change them again simply because you spent so much time re-wrapping the handlebar tape.
