i used 1e8 first and got wa14 latter used n*(sum of edge lengths) and got ac.
i found that for test 14 the curve goes up and at r=200.75 touches x axis then goes up until x=around 450 then down again with asymptote as x axis. so i tried to use tenary search to find upper bound but it does not always work. why n*sum of lengths work? is it weak tests or can somebody prove optimal upper bound?
