I made mistakes, which were my own doing like retrieving my personal input data for the contest answer before I started coding. I got pretty frustrated when it said my time limit had expired 10 minutes afterwards. I should of read the rules more carefully about the submission process, but even then the rules were not very clear.

What they need to do in future is have a better user interface that warns the user that they will only have six minutes to submit their answer after retrieving their input and then include a javascript countdown clock telling the user how much time they have remaining.
