You should do what you are comfortable with. Keep in mind this is just what works for me. Furthermore, the player who puts a conservative cap on their winnings is never going to experience the fun of a long hot winning streak.
With the ups and downs of blackjack it takes hundreds of hours before regression toward the mean will cause actual results to look like expected results. Usually the fun ends when I have lost too much or have played too long. When I gamble for fun I keep playing until it isn't fun any longer. Thank for the compliment and I'm happy to help your bankroll last longer.
