How long to cook separated brisket

[Westonmohr]

Hi everyone, new here. I’m smoking my first brisket this weekend and it was 14 pounds. It is too big to fit in my smoker so I will have to separate the point from the flat and cook the point on the rack above the flat. If I am cooking at 225-250 how long should I expect to cook it for?

Depends on the residual thickness of the flat really.
