Ran a sim that would probably mimic the CSM game you're describing. The sim was 5 decks, H17, DAS, deal one deck and shuffle. BS house advantage was 0.60%
The bets were 1 unit at Hi/Lo running counts between -5 and +6 (TC's of -1.2 and +1.3). Bet zero at -6 and below (occured 11% of the time). And bet 20 units at Hi/Lo RC's of +7 and above (+1.5 TC and above, which occured 6% of the time).
Index plays were made for hitting 12 vs 4, and 13 vs 2, and 9 vs 3, as well as standing on 16 vs 10 and on 12 vs 3, along with doubling on 8 vs 6, on 9 vs 2, and on A/8 vs 5 or 6. Insurance was never taken since a +3 TC occured only a half percent of the time (+2 TC came 3% of the time).
The results were disappointing -- a remaining house advantage of 0.05%. Don't know if some knowledge of "card latency" with the recently reinserted used cards might be able to impove on that.
