I'm about to play in a blackjack tournament whose structure does not lend itself well to most of the usual tournament betting strategies. Specifically:

4 rounds, 5 to 7 players per table, 120 players total, no eliminations, no secret bets, no surrender.

Points are awarded at the end of each round as follows:
1st place on your table = 7 points
2nd = 6
3rd = 5
etc.
7th = 1

At the end of the four rounds, the players with the six highest point totals advance to the final round.

Neither Wong's nor Smith's book seems to cover this structure. The essence of this structure is that, prior to the final round, there is no real premium on getting first place. Though first is obviously better than second, the difference between these places is no greater than the difference between any other two adjacent places. Another way to think about it: every point counts, so you don't necessarily want to risk losing 2 points to have a chance at gaining 1 point.

So, at long last, here is my question: what is the best betting scheme to simply maximize your expected bankroll at the end of 28 rounds, without regard to the other players? Here are the rules:

1D, H17, 75%pen, NDAS, RSA, 2:1 on BJ, starting bankroll=$500, bets from $5 to $200.

Even without card counting, these rules provide roughly a 2% edge (before readers get too excited, the tournament is played with non-value chips).
