Should we pitch first, last or in the middle?

A colleague who is in a startup pitch competition for an accelerator sent me this question:

Steve, In your experience, is it better to pitch first or last in a series of afternoon presentations? 

I answered him in two parts: There is a theory that says if you’re last, you’re only competing against the one they’ve already chosen to win up to that point. But, honestly – it matters much more to be awesome & not worry about the uncontrollable things.

I guess with most projects we have the same choice on where to focus, on superstition, or super performance.
