remco, your score actually was the reason why I started thinking about it.
I know you were coding with the same base code as I and you didn't just copycat my modifications, thus, I think you should have that score.
anyways...
if someone takes the leading code and takes another approach with it and that adds to the score, he still has almost leading score with his code.
it shouldn't be accepted though.
so, think this comes to trust in the end. if allowing higher scores, one has to be able to trust that no misbehavior occurs.

someone might remember way back when some nameless regular posted very low score with:
Code:

function blaah($input)
$blaah = readprofilestring("kixgolf.ini",$input,"correct answer")
endfunction
