Have you thought about comparing the Pre-post newspaper or online priced Fav with the Betfair price movement.
I have seen days where the blowers fall over all day. Then one will see where half get up to win all day. So a cut off point is important, if lay betting, say 5 outs on the day , then stop betting for the day.

Thanks Bhagwan - that is a thought. It looks as though it does need one extra element to moderate things. However because I am looking at every horse in every race, I would need to be able to access that element online.
If I could access the pre-post online it would be interesting to see how it fits in to the mix. But early days and I did change my mind and logged the data again today. I have decided to log to a week and then if a trend emerges in that data, test that trend for the remainder of the month. Already it looks as if it would be a bumpy road so I agree that a stop loss would be needed. |

With your results can you tell me when you took the snapshots, was it 25 seconds and 2 seconds as you said in an earlier post? Also is the $0.50 factor a minimum so all the above results are based on these horses firming or drifting a minimum of $0.50 during the time the snapshots were taken? Cheers, Mat. |

Hi Mat;
On the initial 20/2 there was no movement in the price by .50, so the results for the 3 days posted were snapshots at the 120 sec and the 10 secs mark. I log all the results and in a secondary move I looked at all movement of .50 cents (either way) from the 120 seconds price. I am continuing to log and when time permits I will analyse more; however I feel the analysis may need to be on varying movement prices depending on the price as I did have prices moving in the range -$330 - + $430. I am approaching it all with an open mind and I do not want to filter it out of existence, but I have to decide how to handle these high swings - as my analysis may show these are the ones to follow. Trust this assists ... Fred |

I understand that I am probably the most recent member of this community and also the most inexperienced in the world of the punt, however I make the following comment based on my experience with what is the smallest data base in the world of the punt ... so lots of conditions attached - and I am sure one that everyone on the forum is aware of the statement I am about to make!
So .. the statement ... For the uninitiated, one would have to exercise extreme care in looking at past data to predict a future outcome, as it would be too easy to impose conditions which would give a false hope. An extreme example: On looking at my database (I know - the smallest in the world of punt) I could say the 7th ranked horse in races of 13 starters with a barrier less than 7 and with a drift of more than $2.0 would give a return of over 300% (fact from data base). However my logical mind tells me that in reality the chances of that circumstance repeating would be so close to 0% it is a nonsense to even suggest it. So my hypothesis would be that the more conditions one imposes the less chance of success it has! Anyway a very, very satisfying exercise and another step forward in my learning process. And once again a very sincere thanks to all those who offered their advise and support - it was very much appreciated. Fred |

Its all about sample size.
You really need at least 100 selections before any ideas can be formed. Preferably 1000. Those that bother making note of a trend after a days racing with perhaps 15 races are just washing their hands with a cake of mud. |

Hi Moeee - thanks for your comments.
I have over 200 races (which I would consider a minimum), but due to my inexperience I am really not sure what I am looking for and consequently I am going down these silly roads. But I will continue to collect the data to a 1000 records as you suggest and at some time in the future my experience may be adequate to properly analyse the data I have.

There is a spreadsheet floating around , may even be on this website posted by Woof43.
What you do is you chuck in the number of races , the number of winners , the returns of the winners , and stuff like that , and it tells you what percentage chance it is that your results are due to something significant , or whether it was just plain coincidence or luck. |

Another method of analysis is to have 3 sample batches of 150 races.
If one sample shows a profit & the others more or less break even , it may indicate that it has potential. Therefore more testing of batches of 150 each. If a majority of further batch testing shows a profit , it usually is telling us something. e.g. 5 winning batches out of 8 batches ect. It makes the whole analysis game a little clearer to look at rather than one great big batch of 1000 races in one big clump.
