Blackjack penetration percentage: why does it matter so much.
Trying to track exact penetration while playing always reminds me of staring at the zero in roulette, waiting for that rare event. You know it matters but it's easy to lose the thread mid-session. If I see the cut card hit before 75 percent, I'll usually play it out for a shoe or two then bail unless the table is golden in other ways, like a super slow dealer or distracted pit. Not every session is worth forcing - walking is underrated.
