Yes it is a special piece of software.

(Google) Randon Number Sequencer.

The Lay prices can be anything .

Just Lay up to the price range you feel you wish to go to.

If one does not like the given price of a selection, go to the next race.

Its best not to ask the sequencer for another number for that race because thats how one can get bit.

Maybe bet 1% of bank on one runner per venue
e.g. 7 venues = 7 selectioins.

Max price 50.00

12 runners +

Delete any Favs it picks & go to next race.
