After the Coding Phase, I was 11th in room, and 114 overall.
After the Challenge Phase, I was 4th in room, and 32 overall.
After the System Test Phase, I was 2nd in room, and dropped to 58 overall (250 failed- guess "brute force" wasn't so immune to timeout after all).
The upshot to this? Because 58 < 100, I'm in Round 4, and because I'm second in room- again!- I've netted myself another $100.00, bringing my TCO '05 winnings to $225.00.
If I can keep staying second in the room for the entire remainder of the competition, I'll be in very good shape, y'know? I somehow doubt that'll happen.
But onsite doesn't feel so far out of reach.
