Each of the two training forms contains 18 difficulty levels. The degree of challenge is increased by shortening the maximum permitted reaction time. At the first level the client has 1.8 seconds in which to react to an obstacle, but at the highest level only 0.3 seconds elapse between the sudden appearance of an obstacle and the emergency braking.
At the first session the speed of the client’s initial reactions is assessed and he is assigned to a difficulty level appropriate to his ability. This ensures that from the outset the training program is optimally adapted to the client’s skill and is never either too easy or too difficult for him.
