Jerry,

What I am trying to measure mainly is not just the different scale but the difference in standard deviation -- the relative 'smoothness' of the lines. We hear so much talk about it and if we had a couple thousand data points then we could see about how much smoother TG lines are than Ragozin.

Actually, the Preakness day card was a great card to use b/c it had a ton of entries, lots of shippers, horses from NY and the Delaware Valley circuit which Ragozin has slower than you. Unfortunately, I don't think that the Preakness card is still available on the Ragozin web site and I don't think I saved it to my hard drive.

I am aware of the other items you find interesting and they are, but everybody knows that you sometimes split the variant and Ragozin doesn't (with rare exceptions), so I'm not sure we would learn a whole lot there that we don't already know.
