Luckyboy,

Yes I agree here.

Here are some observations I have made during my incomplete analysis to date which may help....

1. 3YO horses in general are bad investment propositions. Many are overrated and often go around at well under their true price. Much of the hype is regarding previous 2YO form which doesn't carry on as they get older....perhaps burnout???
Examples - Lovely Jubly, 0 wins this campaign and early on when resuming was very short prices.
Victory Vein, 0 wins since resuming and first up was around $2.80, since then has gone around at $7.00 and $6.90 - going on this preparation form should have been at least a couple of points better.

2.Many punters look to improve strike rate or only consider strike rate of certain factors, but the most important part is setting minimum and maximum price filters as a higher strike rate may not necessarily relate to profit.

3. Getting the right balance of factors is the secret and key, but you'll never have a perfect record - it's basically impossible.
The only way to end up on the positive side of the ledger is to set min. and max. prices along with a reasonable strike rate and profit on turnover.

4. The amount of past data worked with has to be substantial. I have been guilty many years ago of pouring over a month of Sportsman's trying to find a pattern or system. This will not work and is a waste of time unless you have access to at least one year of data (preferrably a lot more).
It's like trying to run a census on the city of Hobart and applying the results to the whole of Australia!
