Unfortunately I agree. Jo's charts and daily updates are informative, but do not convey how much this drop in summer miles is impacting Steve's chances.
Kurt, on the other hand, seems comfortably on course to end the year (calendar or 365 day) ahead of Godwin's mark. I suspect one of the challenges for him will be keeping his foot on the gas when he reaches a point when he "knows" it's in the bag. As he appears to be a competitor, I'd anticipate this will only really happen when he crosses the Godwin record (ie it is more an issue of how motivated he is to keep going, to make his "the record that can't be broken")
