Just sent in our final entry, we're happy to end this early...
As for high speed bidding... well, it doesn't take long to realise that what people are posting has nothing to do with the scores they're actually getting, and bidding up slowly is just stalling & delaying the inevitable. So I'm happy with the way things are, if people have tweaked out a level then you might as well move onto the next one.
Anyway looking forward to seeing the solutions, hopefully we're close...
