gear is required in a time period of at least 2 seconds immediately before a deceleration to stop, this gear should be used until the first sample of the deceleration phase. For the rest of the deceleration phase, gear 0 shall be used and the gear lever shall be placed in neutral and the clutch shall be engaged.
                  If during a deceleration phase the duration of a gear period (a time sequence with constant gear) between two gear periods of 3 seconds or more is only 1 second, it shall be replaced by gear 0 and the clutch shall be disengaged.
                  If during a deceleration phase the duration of a gear period between two gear periods of 3 seconds or more is 2 seconds, it shall be replaced by gear 0 for the 1st second and for the 2nd second with the gear that follows after the 2 second period. The clutch shall be disengaged for the 1st second.
                  Example: A gear sequence 5, 4, 4, 2 shall be replaced by 5, 0, 2, 2.
                  This requirement shall only be applied if the gear that follows after the 2 second period is > 0.
                  If several gear periods with durations of 1 or 2 seconds follow one another, corrections shall be performed as follows:
                  A gear sequence i, i, i, i - 1, i - 1, i - 2 or i, i, i, i - 1, i - 2, i - 2 shall be changed to i, i, i, 0, i - 2, i - 2.
                  A gear sequence such as i, i, i, i - 1, i - 2, i - 3 or i, i, i, i - 2, i - 2, i - 3 or other possible combinations shall be changed to i, i, i, 0, i - 3, i - 3.
                  This change shall also be applied to gear sequences where the acceleration is ≥ 0 for the first 2 seconds and < 0 for the 3rd second or where the acceleration is ≥ 0 for the last 2 seconds.
                  For extreme transmission designs, it is possible that gear periods with durations of 1 or 2 seconds following one another may last up to 7 seconds. In such cases, the correction above shall be complemented by the following correction requirements in a second step.
                  A gear sequence j, 0, i, i, i - 1, k with j > (i + 1) and k ≤ (i – 1) but k > 0 shall be changed to j, 0, i - 1, i - 1, i - 1, k, if gear (i – 1) is one or two steps below imax for second 3 of this sequence (one after
