The first thing you want to do is only invest on positive expectations.

As I posted just recently in another thread here, I classify the race on the Favourite and what was the major factors or combination of major /minor factors that determined that Favourite, then the seperation between it and the 2nd Fav.
I then have my subset of data
Remember at the most we have only about 15 factors for the dogs. and how they punters play each of those combinations is so predictable, I just compile all the past results and I know the avg payoffs or positive/negative expectations for each combination by rank order.

So you would have seen in that race what were the Factors in determining it a Fav.

But as you would have seen in that other thread the gold was laid out, but it was too difficult to do?
Don't keep trying to handicap better, you'll improve .5 of a percent, improve your wagering improve 100%, learn to do your database, compile your results create sub sets of data based on a few Factors,
I know you have spreadsheets to do this automatically

Give up the notion of betting only your top selection (especially when over time its a negative expectation) and your halfway there.

Next time I ask you something Woof , Just Ignore me :(

This is an interesting race, with the #2 early Fav. its had approx 71 starts, starts 69 and 71 are its best races, seems strange but then considering it's past "form".it is most probably expected.
I have the #5 and #1 leading followed closely by the #6.
I'm expecting the #1 to improve it's had 2 starts since a spell, raced heavy, floundered out of the boxes both starts and finished both races off ok.

to answer your question they were ranked tied 331

#1 was a terrible underlay in that race for the win spot

Obviously none of this related to the as posted RACE 9 at The Meadows.
So what Race was it actually?

#8 will need some luck to get around this 1st turn, if it does, it wins easy.

I'm hoping for the upset here, plumping for the #5 & #3 to have a good show
