The worst 14 box is arguably Adam's from July 2015, as he was the only person to have a £15,000 high board at that stage. Also, Anita from November 2009 without question had the best 11 box, as she had the top 8 reds and the £1k in play. In addition, I'd say the best 5 box board was Daniel's from August 2007 as he was the only person to keep the Top 4 in play at that stage. Yes, the other amount was £750, but it was still the best 5 box board in terms of both the mean and the Fair Deal.
Just thought I'd add that.
