I have been betting quadrellas for the past couple of weeks and am about break-even. I use half the field in every leg so there are many combinations but is well within my budget thanks to flexi-betting.

However, by omitting the pre-post fave and betting the selections in box quinellas have produced a worthwhile profit, and have won almost every day. The strike rate has been almost 40% for the 87 races that I have bet on. And including the pre-post fave has increased it to almost 65% but does not show an acceptable profit. I'll list today's selections, several are not quaddie races, and see how they go...

Warwick Farm

R3 nos. 4, 5, 6, 7, 11 (no.3)
R5 nos. 2, 6, 7, 8, 9 (no.1)
R6 nos. 1, 2, 7, 8, 11, 13, 16 (no. 3)
R7 nos. 1, 4, 5, 6, 7, 8, 13 (no.2)

Townsville

R5 nos. 2, 3, 5, 6, 7, 10 (no.1)

R7 nos. 2, 3, 5, 6, 7, 12 (no4)
R9 nos. 4, 5, 6, 7, 8, 9 (no.10)

The total outlay is $152

I must be going mad but I can't remember how to work out the cost for a box quinella.

I thought if there were 5 runners, the price would be 5*4 = 20 for $1.
6 runners, 6*5 = 30
7 runners, 7*6 = 42

Now if that were the case with a makeup of :
4 races with 5 runners = 4 * 20 = 80
4 races with 6 runners = 4 * 30 = 120
2 races with 7 runners = 2 * 42 = 84

Total outlay of 284 or 142 for 50 c.....

BJ: Box quinella 5 runners costs $10, eg. 5*4/2. The division by two is because any of the two horse combinations can run 1st or 2nd.

The same 5 runners combination would cost $20 if they were taken as exacta bets.

So I was wrong, but that still makes the total outlay $142?

That's right, I make the outlay $142 based on a $1 unit.

Hi.

My records show there were 2 races of 5 runners = $20
6 races of 6 runners = $90
2 races of 7 runners = $42
Total of $152. Maybe I missed listing a selection?

Yesterday was the worst day since my keeping of records. For an outlay of $152 the return was $104. Hopefully that will be rectified today. Interestingly, there would have been an outlay of $1,360 betting box trifectas for a return of $1,170. Unfortunately I haven't kept any previous records of box trifectas.

Today's selections are:
Grafton
R3 nos. 1, 3, 5, 7, 8 (no.2)
R4 nos. 1, 3, 4, 7, 8 (no.2)
R6 nos. 1, 5, 8, 9, 11, 12, 14 (no.2)
R8 nos. 2, 3, 4, 8, 9 (no.1)
Eagle Farm
R4 nos. 2, 3, 5, 8, 10, 11 (no.4)
R5 nos. 2, 3, 5, 8, 10 (no.1)
R6 nos. 2, 3, 4, 5, 6, 8, 10 (no.7)
R7 nos. 2, 4, 5, 6, 11 (no.1)
Belmont
R2 nos. 1, 3, 4, 5, 9 (no.1)
R4 nos. 3, 4, 5, 7, 8 (no.2)
R5 nos. 2, 3, 4, 7, 11 (no.5)


By my calcs the quinella outlay is $142, and the trifecta outlay is $1,080.
