Luckyboy,

I might be able to assist you with improving your refining of chances in pre-post markets. You state that newspaper pre-polls secure approximately 70% of winners by refining your analysis to the first six horses in the market. As I have said previously, these markets are not a true reflection of the market.
To alleviate this I suggest you certainly refine your study to the first six in the market but make sure you use the opening market quoted on the radio or preferably the opening market shown on Skychannel.
These are infinitely more accurate as they take into account overnight market movers and support for first starters etc
I am certain if you utilise this strategy you can refine your success rate to about 85%(only taking notice of first six in market).

Cheers and let me know how you get on.
