G'day everyone,
I'll put my eggs in the basket
with Kenchar&Twodogs ect.It comes down to what the indivdual feels comfortable with.Myself, I prefer to look at angles.When situations arise that appeal to me I have a go at them.Thats where I think the system bettors can fall in a hole.Plus it seems to me to be a whole lot of time to invest in something that may or may not work.
To have a basic understanding of statistics is important,however a lot of statistics that are printed in regards to racing are basically useless.When the system builders figure out which is which I've no doubt they can and do make some money.The main "but"about systems though is they all fail when the weight money is to great.(same as weight ratings)

When someone tries to use mathematics and times ie.certanties in an uncertain game I reckon you've got to be doomed to failure.
Both of these do have there uses though,that being all hores are divisable into different classes(times )and the mathematics can tell you what's good value.Thats all I'll use these measures for.Cheers strawb
