Houston, we have a problem.......
do you work out the most successful trainer/jockey combinations without a laborious one-combo-at-a-time effort ? No idea really, and I don't think I will find a solution. I have each runner from the last 3 years set up on an excel sheet with odds, finish position, tote price, SP, trainer and jockey, and betting outlay for each horse proportionally staked, plus return, if any.
In the meantime, if anyone would like a combo checked, I can do it for you. I am guessing the real gems will be hidden among the not-so-well-knowns.
