Nothing wrong with Target betting ,so as long as you have a "what if plan" in place .
e.g. what would you do if you had 10,20 or 30 outs in a row.

One could halve their target over say the next 10 bets & recover in stages.

One could stop betting after losser No.13 & wait for one of your selections to get up before commencing betting again.

13 by the way is the mediam for a 20%SR.
In other words ,the majority of winners are struck within this range ,with the odd few blowing out,up to 45 outs in a row, based on 20%SR.

Stopping at the first winner ,definitly has its merits , at the same time ,one has to respect the fact that a long run of outs is still possible , maybe not this year but maybe the next, so one has to have contingincies in place with their "What If Plan"
