Yes! If you count sevens as -12 and all other cards as +1 then the odds on the side bet swing to the player’s advantage with a true count (running count divided by remaining decks) of 5 or greater. According to my simulations in six-deck game with no three-card guarantee and 75% penetration the true count is 5 or greater 23.2% of the time and the player advantage at these times averages 27.3%. In the game with a three-card guarantee the average advantage goes up to 29.1%.
