Yes, but you won't like it...
privador,
If you click on the link below, you'll see the results for Win, Loss & Tied Percentages by True Count (6 Decks, 83% penetration, 1-8 spread, no cover, S17, DAS, High-Low). As you can see, if you wong in whenever the TC exceeds +14 and wong out when it falls below, you can maintain a win percentage above 46%. Of course, you'll also play only 0.03% of the hands seen.
In fact, according to a sim I ran on CV, if you're willing to forgo all double downs, you'll win more than 46% when the TC exceeds +12. Of course, you'll also lose money on the deal, since DD hands are big money makers.
Sorry to be the bearer of bad tidings!
