\begin{equation}  C=\left|\frac{\chi^2}{fN}-1\right|\frac{AP}{f}.  \end{equation}   {\bf [EL: Not sure where this combination comes from. A standard statistical measure is the mean squared error or risk: $R=\sum_i\sqrt{\sigma_i^2+(\tilde{\Delta t_i}-\Delta t_i)^2}=\sum_i \sigma_i\sqrt{1+\chi^2_i}$.]} \sigma_i\sqrt{1+\chi^2_i}$. Again we can apply this only for the "apparently precise" fraction $f$.]}  The results will not be revealed until the end of the challenge in order to maintain blindness.  The deadline for TDC1 is 1st May 2014, i.e. six months after TDC0. Multiple submissions are accepted from each team in order to allow for correction of bugs, and for different algorithms. However, only the most recent submission for each algorithm will be considered in order to avoid favoring teams with multiple submissions. Late submissions will be accepted and included in the final publication if received in time but will be flagged as such.
