Hi, Burrah.

Do you lay every third-fave or do you apply some sort of filter?

Good luck with your lays.

Mark's progress:

$3000 bank.
24 picks, 13 bets, 12 winners, 92.3% strike rate.
Total profit = + $129.00, or +4.3% of balance.



For the poor among us:

$300 bank = $12.90 profit divided by X amount of hours effort = y$ per hr. profit [?]

On the up-side though, the hourly rate here should gradually improve:-)

A years worth of equal 2nd or 3rd raters, explains the several missing races. A repeat of yesterday's strike rate would be pleasing.

One of the problems with Oz racing is surely that the pools are so small that an hour or so before the race there may be nothing to match.

For example, at this moment, the first at Quirindi has a whole $30 in kitty. Doesn't this effectively stymie the idea that Maria encouraged of set and forget?

P.S. Nice work yesterday, Mark

I use the following system , which can end up more of an art than science.
First I look at the the deduction factor ( which I use as the PP)then the the actul fav with the lowest odds and the horse with the highest amount of money on it. When a horse has all these stars aligned, it is obviously the favourite.Same for second fav and third fav. Things get interesting when one horse has, say, the lowest odds, another has the highest reduction factor and a third has the most money on it. then I have to make a personal call. BTH all this only takes a minute as I only look at a race for the first time 3-4 minutes before the start.
Regards

.


Not a good day.
37 selections
20 bets
4 winners (80% win rate)

Loss of $26.33
New bank would be $3102, and bets would remain the same.

Winners in my top 2 were down.
Winning 3rd picks were up, hence the small loss today.

I still believe there is merit in this and will be starting from scratch on Monday.

Mark,
Just some observations - for what it's worth.

I have looked at thousands of races now through an access database of Betfair prices and fluctuations.

If you layed every horse in every race in the final minute before they jump, you'd make a killing. You just need a huge bank to cover the longshot liability.

Laying favourites, you get close to breaking even with a very slight profit.

An interesting observation is that the average price traded on any runner is extremely close to the final price, which surprised me greatly. Especially as I thought the longer priced horses go out to 100/1 and 200/1 in the final minutes, but what is shown is not necessarily what's traded.

If you LAY every horse in the $3.00 to $8.00 range, you make a decent profit also, but if you back favourites over $3.00 you also make a profit.

This is with no other filters and every aussie horse race Betfair have a market on.

One thing stands out massively though, I could not understand how I made a killing laying certain horses, as the database showed almost breakeven with just a smidgen of profit.

The answer lay (forgive the pun) in obtaining better (or worse) than the average traded price or final price.

Being able to weight my bets according to underlay, I made significant profit, and testing this over thousands of races, it solidified my philosophy.

The Golden Goose doesn't lay it's eggs with 5 minutes to go, or as they are loaded, the bird flies in an erratic pattern dropping golden eggs along the way, if you have the will to bring a basket and spend time collecting those eggs, it all adds up to pure gold

Well, i was going to give day 3 lays for the 2 day trial, but the site I use for the form just refuses to open. grrrrrrrrrrrr

Chrome, I would like nothing better than to lay every runner at the back prices in the last minute or so, but I just cannot type fast enough. I reckon a team of experienced Betfairian's working together would be able to clean up making last minute books on just about everything.

Finally managed to get in and do the numbers. I won't insult anyone by putting up the lays, but will report if anything out of the ordinary happens.

Hopefully won't have problems on Monday.
