If dutching the first 3 another option would be to chase $100 over a series of say 5 bets to keep it safe the total % outlay for the race eg. A=4/1=20%, B=5/1=16%, C= 6/1=14% total % outlay is 50% so the outlay on A = $4, B=$3, C=$3 total outlay =$10 and if any selection wins the expected return $20 less outlay $10 = profit $10. With a level stake break even or better selections this method could be used progressively. What concerns me is that we are not going to get the prices as in the example as prices these days have been compressed. if 50% or more of your stake is outlayed relative to the return you are accepting an odds on situation. It is interesting to note that Tatachilla at the PA site backed the first 4 outlayed 80 units to return 100 for a profit of 20 units that is certainly ODDS ON. Even not using the TAB [progressively dutching the first 3 or 4 selections returns can be disappointing on some days and losses can escalate alarmingly on a bad day. I would welcome your thoughts.
