Agreed. Actually I made an experiment before that related to this. I record all my bets win/lose for 1 week with same amount per bet in all of my session. I realized that my PnL result is almost breakeven but a little bit on lose side. I conclude that win or lose streak has different timing and we should stop already gambling if we hit the lucky streak in early stage of our gambling session.
I also use this kind of strategy, when I hit a lucky streak whether it is early or not, I stop on that slot and move to another slot game. It is somehow effective but of course, it won't guarantee that we will end our session with a win. It all depends on whether we stop while we are winning or not.
Sometimes bad luck hit hard on the start of the game but like what you said, We can not conclude early since there’s a possibility that the win streak was supposed to be follow right after we stop betting.
True that, but that is also when the game hits our bankroll the worst. I had an experience with thinking that the next set of autoplay will trigger my lucky streak, emptied my bankroll from then on I always set a fixed number of spins on every slot game. Whether I hit the scatter or bonus round or not, I switch to another one. Sometimes I got lucky with that strategy, sometimes not but at least I had played different slot games.
