Number of decks is really not relevant to counting accurately.

Any reasonable counter would be able to accurately count a 100-deck shoe. It's not that hard.


And, yes....as long as there is reasonable penetration there will certainly be advantageous situations.
(penetration: meaning that they don't shuffle the 8-deck shoe after dealing only 1 had or just 1 deck or something....usually they'll cut-off the last 1.5 to 2 decks of a 6-deck shoe for example)
