[quote]Guys, have you noticed any change in the liquidity in the Greyhound markets of late? [/quote]
I didn't notice a change of liquidity.
[quote]do you have play and test the distances ? 480 m ,500m m etc .
is there a distance who make more profit than an other ?[/quote]
I use >=480m. So 500m etc. is included, but in my excelsheet I didn't record the distances. I will rewrite this sheet (there a some mistakes in calculations and correcting them would be taking more time, than to rewrite it) and will record this parameter in future, too

[quote]Jimboo, 10/1 to lay is to high ,take maximum 6,5 to make some profits and constant [/quote]
One question for my understanding: 10/1 prices means a price of 10,00, right?
If you use the stake as liability I think the prices are not so important. My risk is every time the same.. I will take a look of that in the future for longer term and analyse the behaviour of this. Eventually you're right

[quote]I DON'T KNOW WHY THIS SISTUATION EXIST .CAN SOMEONE PUT TO EXPLAIN ME ?[/quote]
I think the problem is, that the prices of the system are only predicted for a lot of hours before the race starts. Otherwise i think, the prices at betfair (the real odds) are sometimes very curious.
