I once read an article about counting only high cards. 9,10,J,Q,K,A.
The article went to show by counting high cards in an 8 deck shoe (192 out of 416 total) one could adjust there bet accordingly as favorable cards would be comming. If 70-80 high cards have been dealt into 2/3rds of the shoe, then the rest of the shoe would be saturated.The down side with this method is that you would never get a true count!! Is it possible to use perfect basic strategy and this casual count so to speak?
