In my opinion the substance of this topic can be summarized like this:
Do we believe that, a specific bet after a specific event (trigger) has a better hit rate than if we bet continuously?
For example my trigger is Red. Each time Red hits I bet on Red for the next spin. When Black hits I do not bet the next spin.
Do we believe that RB...RB...RB...RB...RB...RB were I lose 6 bets, is less frequent than BBBBBB ?
This is the heart of the problem. Whether you apply it to different bets with different triggers, the logic is the same. My own opinion is that probably yes, the trigger-bet-stop method may be just a tiny bit more safe than the continuous betting method.
A very common misunderstanding here is that even if it offered no advantage, the trigger-bet-stop method has less losses just because you bet less often. What we are searching here is the loss rate/win rate, not the absolute number of losses or wins.
