This second round is a free-for-all. So, if you see a way to improve a solution (either your own or somebody else's) then go for it.
No holds barred!
Who ever can improve a script the most, shave of the one elusive character, or even come up with a new approach (haven't yet seen a recursive approach) that lowers the score wins the second round.
