There's the mathematical competition to define the largest precisely defined number, i.e. "largest number defined by humans so far, plus one" is not ok, but "largest finite number of cells visited by Turing machines of 7 states on an initially zeroed tape" is ok. It's obviously about finding new tricks rather than rehashing the existing ones. It seems like the tricks from this competition would be reusable for the slowest algorithm competition.
