Daz,
Chunal winning time 26:56 = 1,616s.
My time 38:34 = 2,314s -> 57 points.
James's Thorn winning time 34:48 = 2,088s.
My time 47:11 = 2,831s -> 74 points.
Is that right? I'm intrigued by the calculation (I used Sam's big equation higher up). If my time were double the winning time I'd get zero points. Any slower than that and they'd become negative. Is that the intention?
