I'll try get up a few Markets for tonight , and some suggested ways to wager.
My First Race will be Race 5.

Back in half hour or so.

2 MID LEVELS $4.3
3 THECLA BALE $4.8
6 ZERO'S HERO $4.8
8 LEKTRA FLY $6.5
5 MAGIC DASHER $14
7 WHERE'S FREEMAN $18
4 SPECIAL COLOUR $25
1 KARINGAL TOTE $28

I figure a Standout Quinella might be an Overlay here.
#6 Zeros Hero into the other 3 Favourites $1.50 with the top 2, and $1 with the Pink.

And don't forget to be alert for HUGE Overlays about the top 4 selections.
Double the Market Odds would Qualify as HUGE.

This will be the Last of the Markets I spend considerable time working out.

6 STACK 'EM FLAT $3.3
2 AMERICAN MCGEE $5.6
5 ALLEN ZANDER $6.9
1 GREYWINDS DODGE $8.4
3 LEO WABBIT $8.6
8 LONG GULLY ARCH $10
7 SINBAD'S ANGEL $33
4 WANDY LAYLA $50

The bet is the top selection.
$8 a Win
It will win comfortably if it can keep out of trouble.
Any Price above the Quoted is fine.
The animal misses the start, but that is not a bad thing to do from that draw at this particular start , because it should avoid carnage as the first turn approaches very quickly.

Winning Style Box 1st Split Rating Rank
FR 1 $4.86 3
BR 2 $9.36 4
BR 3 $61.97 7
FALSE 4
BR 10 $12.15 5
VR 6 $2.95 1
FR 7 $4.69 2
FR 8 $27.09 6
The #1 really wants to be off the rails, but I don't think there is going to be too much of a push from the 2,3,10 early. The problem will be if the #7 can steer clear of the #6 as both the #7 & #8 will head to the rails.

Moeee so you understand why I post those 1st split market, the dogs that are all Front runners and need to lead from the front, that is the market i use for those dogs.
So in this race
#1 =$4.86 best odds so far $4.06
#2 although a BR that is for shorter distances $9.36 best odds $8.33
#7 $4.69 best odds $4.79
#8 $27.00 best odds $5.47
With the back runners, you need to look at the 2nd split market and blend it into the 1st split.

Box combined 2nd sect
1 $5.46
2 $6.90
3 $6.00
4
10 $6.60
6 $184.90
7 $3.23
8 $25.44

I ain't got time plus I'm tired and need go bed for work tomorrow.
But I'll post something tomorrow as I ain't read your post and understood it as yet.

I understand.
But everyone has their own methods, I know I do.

I ain't got around to mucking about with 1st and 2nd splits yet.
I've seen some of your results, and they are not a lot more accurate than are mine.
Most of your better results are when your handicapping suggested an animal was an Underlay, yet you watch the Market, and something happens that this Underlay is now a good bet.
That to me is simply pointless and against why I handicap a Race.

But if it works for you , then that is what works for you.
