I've noticed today with two races, even though my Dutch had the winner I still lost about 13% of liability due to unmatched bets going SP.

With the bot you select the horses to Dutch, it does a calculation and returns a potential profit for you to approve. You hit the GO button, the bot fires but not all the bets are matched straight away. Some unmatched bets then go SP.
Example: The bot has staked a horse $41.90 @ $6.60 when bot fires. If unmatched BF gives you the SP price, in this case $5.17 but you're still staked at $41.90. Your Dutch is now out of kilter by $59.92.
There's swings and roundabouts, sometimes it works the other way.

Has anyone encountered this Dutch betting? Any solutions?
