[AusRace] I'm back

[Andrew Child]

Hello, I'm back, after several years (maybe 6 or 8).  Couldn't keep 
away, but much more reserved in my betting and comments now.

I believe that the top 5-6 horses horses in pre-poll betting have about 
an 80-83% win rate, over all races.

If we look into the better class of races, such as Open, Listed and 
Group races, is there any difference in the win rate for the top 5-6 
winners? Or is it the top 3-4? Or less?

Regards, Andrew
