'Making a profit' needs context. Profit for a day or more importantly over 12mths.? A punter who has selected say 6x$10 bets for the day and is ahead say $20 by bet 2 and doesn't decide to take the dog for a walk instead of continuing with the other 4 bets, is a 'robotic punter' [brainless in other words]?

Without being able to see into the future, there is no way to know if a selection is going to win or not and making a reassessment of selections while the action is on, is not a good move and implies poor initial assessment before the action for the day starts.

Next day the 'smart' punter who did take the dog for a walk the day before [even though 2 of his next 3 chosen bet selections won while the dog was enjoying himself and the punter didn't bet them], still hasn't won a 'profit' by bet 3 and has lost $30 so far, now decides to call it quits or does he keep betting? A reassessment of the next 3 bets to decide the issue?
In context, the punter's $20 profit from the day before is now a $10 loss unless daily losses or profits have no meaningful relationship, as a 'profit is a profit' and any day of loss, doesn't count[?]
