I don't know there strike rate but I do know you can't just blindly back every 2nd or 3rd favourite and make a profit in the long run.
Just the same as you can't back every favourite or even every 10th pick, if it was that easy this forum would be for people wanting to lend you money because they have so much.

I am sure someone will have some rules or filters you could apply that might help to make a semblance of a profit but then if you had a think about it, you could probably do it yourself.

Use the force Luke.
