I'm playing 8 deck with 50% penetration, when they reach the cut they don't just reshuffle that deck they have one pre-shuffled, at that point I reset my count because it is a new set of decks. I'm wondering whether I should be thinking of it as 8 deck or 4 deck seeing as all 8 are never used.

Just a beginner learning the basics. Working with the hi/low strategy at the moment.
