My most recent trigger is waiting for a 3 wins or lesser in the last 10 decisions as an alert. My trigger would be a situation after an alert wherein the trailing bet achieves average hit rate, it should have in the last 30 decisions.
 For example,
LLLWLLLLWLLLW here the third win alerted me to look for a trigger hereafter. If I get at least 14 hits of the trailing bet in any subsequent patch of 30 bets, that would be my trigger.
This way, the worst of the worst patches should go virtual most of the times.
