A combinatiion of both. While I think lengths beaten is a more accurate way of determing a horses performance than the finishing position, I stiill like to give some credit to horses who have run a place. Before you ask , Iam still working on how to combine the two in some sort of meaningful way.

If everything is exactly the same then the time would have to be the only judge you could work by, better time - better run. I would much rather my horse finish second then sixth though.
