Just what ive found,
I must have too much time but im always thinking of differant ideas to punt with,
An absolute classic.
I went through MONTHS of data on qtab(can i say that) and tested ON PAPER backing 1,2,3,4 same amount each way on dogs and trots.
It showed a healthy profit.
I deposited funds and gave it a go.
Results.
Time tested on paper, six months of qtab data.
Initial invest, 400 units,
Max bank reached, 3300 units, three weeks
Withdrew 2000 units,
Then !
I started again,....Results
Well, cause i was so good, i thought what the heck, lets tripple the initial bet and go from there,only a year of this and dingo will have six bikini clad blondes pouring my beer (the good stuff) whilst i lay back on my 100 meter cruiser in the Bahamas...yeh right,........lost it all.
What happened,..well,.....when i tested the system, it worked, i changed nothing in my selection process but i did up the bets, i kept really good records, every bet, average div, pot, units per bet out and per return, longest outs,.everything.
What i didnt learn until the boy went over it again was the pool size, because some bets were due to "safe" progression 500 units, i didnt realize that the pool BEFORE i put my funds in may have been 600, so when the selection that i ORIGINALLY had say 100 units on went into that pool it didnt effect the price that much, but with the big ones, i found that the returns instead of say 1.5 would be 1.04, which then called for even bigger bet next race, the bank went bye bye.
Dingo now spreads his outlay over more than one place !
What im saying is take note of every possible outcome that you can, my back testing DID NOT take in consideration this factor and look what happened.

Hope ive been some help.
Cheers
