Go through the entire race programme and note the jockey who is riding the most horses who were last-start winners. This is the jockey you will be following today.
In the event of more of more than one jockey tying for selection, select the jockey who is currently the highest in the jockeys' premiership table at the present time.
The recommended staking plan is that you bet one unit on the first mount, two units on the second mount and so on, increasing one unit after every bet until there is a winner, where you stop betting for the day.

Shouldn't you be putting these in the "Betting Systems Forum" ???

So just clarifying you back all this jockey's mounts for the day, not just the last start winners.

Yes, you do back all the jockey's mounts, though you do stop betting once you back a winner.

I do apologise for this because I thought I was in "Betting Systems Forums".

As for the correction, all of the systems are now in Betting Systems forum.
