Not a bad experience. First shoe in, deck goes to the "eggs" count (plus nine), and I managed to hold the count through Streak bets two, three, and four, finally getting nailed by the dealer 6 up-face card under-five dealt for a dealer 21 to my 19.
But on Streak bet 2, I made 5 x 3 ($15). On Streak bet 3, I made 8 x 5 ($40), and on the 4th Streak, 18 to 1, (5 x 18 = 90). Losing the five dollar Streak bet on the fifth Streak was .. well, not a big hurt.
Observations: you really have to wait for the shoe to turn positive BIG (six or higher) to be effective on Streak bets 3 and 4. With even only a "fair" positive" count (say, 4), the second Streak bet is playable, and I went there a lot for a good 3-to-1 payoff (15 bucks for a five buck bet).
Didn't notice much difference in doubling on 10, 11 vs bust when pen was good. DID notice difference in soft doubling against bust card -- it's not favorable for player if you're Streak betting.
Doubled my money for the day. Wasn't much -- I only took out 300 for the whole session, because I was experimenting, and didn't want to get hurt the first time trying it.
Only played a seven-hour session. Want to try it over two days and see what I get.
Thanks for the math, guys!
