BAT is useless..
a) often the figure are immensely wrong.
Horse trades last at $3.50, reported as $1.34
b)BAT gives the very last traded price.
C)BAT gives Betfair favourite, not bookie favourite at OPENING.
d)BAT does not record what was available beforehorse was backed in.
This all adds up to 34% after commission.
Download the Betfair historical data and take the median price traded for the worse case scenario.
I've often been matched at up to 40% better than the last traded price.
