Online you know who you are up against within three hands. Live, every session starts from nothing — unless you keep track of what you see. Seat 6 is built for the player who takes that seriously.
Lay out the table exactly as it sits. Record how each player plays, where they overpay and what they give away. When they sit down again weeks later, your read is still there. The hands that matter you record and replay step by step at home.
And you see at a glance how tough your table is: every player gets a level from fish to crusher, based on results you track yourself. So you know whether you are sitting where you want to be.
No ranges, no solver, no advice. Just what you saw — back when you need it.
