Maybe domain authority of other sites contribute to their ranking more than you realise.
Also, you said you won 300 links which happened, from what I understood, when you launched the domain.. Have you had steady growth of links since then? If new links are not arriving then perhaps Google might look at these links as somewhat "stale" and they might count less.
What I am trying to say is that your press coverage might not count as much as you think any more.
