Here is the thing though.
In this day and age almost everyone has some sort of Data Base including the Racing Journalists so why not take advantage of their expertise.
I.e In the Tipster Poll if they have only 2 horses on the top line then the indication is that these 2 are considered the best 2 for that race.
One then only has to get a minimum $3 about both to make a good profit.
Of course not all will be at that minimum price so why not just take the better priced.
Over a period it should even itself out.

My belief is that we can outsmart ourselves looking for complications.
