You ignore the fact that you cannot use the permanent brain to be 2 times faster
in your opponent's time.

Playing without permanent brain is similiar to having 50% less time with
permanent brain (assuming  you predict 50% of the moves)

Playing without permanent brain is not similiar to being 50% slower with
permanent brain because if you are 50% slower then you are 50% slower also in
the opponent's time.
