Various courses have hurdle and chase tracks which vary enormously in their topography, not to mention the measurement of distance being occasionally ambiguous. Fontwell, Kelso, Ludlow and Sandown are tracks where the courses diverge entirely and where times cannot be easily compared.
I see your point, Rory, but there are two sets of standard times for each NH racecourse to allow for the differences in their chase and hurdle tracks.
Only since this spring have the calculated going and the official going been so widely disparate at so many different courses, with the hurdle tracks returning times that are some 5/6 seconds per furlong slower than the chases on the same card in some cases.
Even allowing for the deluge of biblical proportions last summer, the going calculations have never been so widely different from either the official or chase track goings as they have this year.
Until this spring/summer, I have rarely had to make 2 separate going calculations for the chase and hurdle tracks (apart from Sandown and Leicester), but over the past 5/6 months it has been necessary to do so for at least 1 meeting a day.
The only thing I could think of to account for it was Shadow Leader's posting concerning the deteriorating quality of the ground raced on.
Just thought I'd pick a few brains, so if anyone has any suggestions?
