Evening all. Does anyone know whether bookies SP odds or TAB odds are "closest" to actually observed racing results (in general). You can approach this any way you like, though I imagine it's a case of whether always betting on, say, the fav returns less/more with one or the other, per annum. Likewise the second fav, the third fav etc etc etc, taking into account the differing "edges". Hoping for enlightenment!! Cheers
