Test Another System


Try combining a few of these ratings and you might show a profit.

I combined 2 ratings (Win Strike Rate Rank + Don Scott Rank):



There were 45200 horse form lines in the database at this point in time. We update when we get time.

There were 1770 selections for the System
There were 542 Winners for the System for a strike rate of 30.62%
There were $1879.34 returned for WIN (after 5% commission) which means a Profit or loss of $109.34 or a percentage profit/loss of 6.18%

Test Another System The Rules used were : donScottRank = 1 and winSrRank = 1




Could also try laying the poor ratings witha few filters:


There were 808 selections for the System
There were 524 which Lost (did not win race) for the System for a strike rate of 64.85%
You had to pay out $724.74 but brought in $767.6 after 5% commission. This means a Profit or loss of $42.86 or a percentage profit/loss of 5.3%


Test Another System The Rules used were : barrier < 5 and rating = 100 and priceRank < 90 and priceRank = 1 and priceLayRank < 90 and priceLayRank = 1 and uniRank = 1

Maybe just back favourites on a good track:



There were 45200 horse form lines in the database at this point in time. We update when we get time.There were 2762 selections for the System
There were 963 Winners for the System for a strike rate of 34.87%
There were $2809.2 returned for WIN (after 5% commission) which means a Profit or loss of $47.2 or a percentage profit/loss of 1.71%

Test Another System
The Rules used were : priceRank < 90 and priceRank = 1 and priceLayRank < 90 and priceLayRank = 1 and cond = 'G'

Or back favs going up in weight:

There were 1056 selections for the System
There were 368 Winners for the System for a strike rate of 34.85%
There were $1133.3 returned for WIN (after 5% commission) which means a Profit or loss of $77.3 or a percentage profit/loss of 7.32%

Test Another System

The Rules used were : weightChange > 0 and priceRank < 90 and priceRank = 1 and priceLayRank < 90 and priceLayRank = 1

Another simple one.

Any favourite who has not won at the track and distance:

There were 2770 selections for the System
There were 989 Winners for the System for a strike rate of 35.7%
There were $2870.85 returned for WIN (after 5% commission) which means a Profit or loss of $100.85 or a percentage profit/loss of 3.64%

Test Another System
The Rules used were : distWinner = 'N' and courseWinner = 'N' and priceRank < 90 and priceRank = 1 and priceLayRank < 90 and priceLayRank = 1

That's a good one UB although you would have to be on hand to know who the fave is and if it hasn't won at the track and distance.

BY THE WAY - Does anyone know when the late mail selections get posted?

Two words - Betfair Bot

Have no idea on the late mail selections.

But the bot wouldn't know if the fave in the next race has or hasn't won at the track and distance.

You would need to feed it a list which I think most bots can do.
Or do as I have done and write your own bot to do it all for you.

Gday UselessBettor

You have written your own Bot! Is this hard to do? Do you need to be a programmer or can anyone do it?

Thanks

James
