I've been using KO for two years and about 175 hours.

I would like some recommendations on upgrading my strategy from KO Preferred to a strategy that can provide a little better performance.

I'm not a statistician and have only read 2 books so far (Beat the Dealer and Knock Out Blackjack) really don't have that much time.

In Atlantic City and Eastern PA, the game is exclusively 8 decks and that is where I play most of the time.
Penetration is typically 75 to 88% (Less in AC, greater in PA).

In PA, surrender is allowed, in AC, surrender is not allowed. In PA, there is S17 in AC, I play at H17 ($10 minimum) tables.

With KO Preferred, I have to wait for a delta of 22 low cards until I can raise my bet.

From what I have been reading in this forum, if I can do something just a little different,
I would be able to modify my betting from KO and possibly get better results.

Thanks
