Anyone invested some time in a system to pickup a 100% s/r for the Treble/Quad Legs?

Would of cause include multiple selections. I've been working on something for awhile now but can't get the selections low enough in relation to risk and return being worth while

I figure if you take the Field in every Leg would be the only possible way of 100% Strike Rate.

What a great idea. 20 horse field size gives 160k 100 per cent div to have all fav get up and payout 200 bucks
