I'm going to try this idea.

I frame my Market.
Then close to Race Start Time, I compare the Actual Market to mine.
Any animals short in the Market are rehandicapped to see if I have undervalued their ability for today.

I then take my top 2 Overlays and key them with the Top 2 Chances.
And take the Top 2 Chances and key them with my Overlays.
Total Cost is 10 Units.

If at least 1 of my Overlays comes in, Is possible that I should score the EXACTA.

GEELONG Race 6

3 MISS SHANAE $4.2
8 BOOMA HERBIE $5.4
1 KING RYAN $6.5
5 INSTANT GABBIE $6.6
9 LIMBURG LUKE $12
6 NOT A ZAC $14
4 GOMAPILE $15
7 EXQUISITE DROP $20

The EXACTA should filled by my top 4 selections.
Early thoughts are 1,5 - 1,5,3,8
and 3,8 - 1,5

GEELONG Race 9

1 REGAL CADET $4
4 POLLY'S CHOICE $5
5 COMPLEXIFIED $8.3
2 SOUTHWOOD DODGE $8.4
3 BIG JAX SLAYER $9.6
8 CANDY THIRST $14
6 SO SAUCY $14
7 LEFTY ODOULL $16

This race is a little tricky but at least 1 position will be filled by my top 2 selections.

Early thoughts are 2,4 - 2,4,1,5 and 1 - 2

You see what happens when you bet early?
LOSER

Fortunately I waited till the race Market was available and when seeing the Odds that were available due to NOT A ZAC being favoured by Most, but not me, I decided to Box my Top 4 and collected $32 for my $12.

Had the 3 placegetters in my top 3 selections

Not that it done me any good seeing as how I'm playing EXACTAS, but its nice to see that the handicapping is working.

I expect more Profits in Race 9 if you missed out.

Well, this time I waited for the Market and found the check much too short for me to feel good about backing so I ended up bombing out

If you dunno what the heck you are doing, then you best stop.

I'm gonna just go Boxing up my top 4.
But still keeping an eye on the Market in case I sfould drop my 4th selection in favour of something fancied by them what knows more than me.
Or at least knows something that I don't, Trials,Fitness,Whatever.
