During my long noviciate of acquiring purported TT mastery, every year or so when I rechecked arm/cartridge set-up I found it way out of adjustment. I suspect it was my measurement tools & skills that were improving, rather than shifts in geometry.
Top-ranked TT masters are occasionally spotted at bicyle race shops discussing the mysterious properties of Italian hub grease. They wake up wet after dreams of being caressed by three-armed octopuses with names like Grace, Graham, or Schroeder. They puzzle physicians in ERs with toes broken by dropped 5 lb. record weights. They sometimes forget to remove their stethoscopes when exiting the listening room.
