As far as downshifting is concerned it can be done either way. 5-4-3-2 or 5-2. The problem arises in the 5-2 shift when done too early in the braking zone and creates a possibility of mechanical over-revving. The engine does not like this and will expire pretty quick. Less driver movement in the car means less opportunity for mistakes so the 5-2 shift lends itself to the economy of movement theory.
