city cycle shall be combined with the previous two completed city cycles. See the example in Figure A7/1 below.

Example with an even number of completed city test cycles before the city cycle where the combustion engine start
              If the number of completed city cycles is odd, the incomplete city cycle shall be combined with the previous three completed city cycles. See the example in Figure A7/2 below.

              If the number of cycles derived according to Figure A7/1 or Figure A7/2 is less than four, the drive trace indices IWR and RMSSE shall be calculated for each individual cycle and reported.
              If the number of cycles derived according to Figure A7/1 or Figure A7/2 is greater than or equal to four, the drive trace indices IWR and RMSSE shall be calculated for each individual cycle. In this case, the average IWR and the average RMSSE for the combination of any two cycles shall be compared with the respective criteria specified in paragraph 2.6.8.3.1.3. of Annex B6 and the IWR of any individual cycle shall not be less than -3.0 or greater than +5.0 per cent.

              7.4.3.1. Consecutive cycle test

              The consecutive cycle test procedure shall be performed according to paragraph 3.4.4.1. of Annex B8. The drive trace indices IWR and RMSSE shall be calculated for each individual test cycle of the consecutive cycle test procedure and reported. The test cycle during which the break-off criterion is reached, as specified in paragraph 3.4.4.1.3. of Annex B8, shall be combined with the preceding test cycle. The drive trace indices IWR and RMSSE shall be calculated considering this as one cycle

              7.4.3.2. Shortened Type 1 test

              The drive trace indices IWR and RMSSE for the shortened Type 1 test procedure, as performed according to paragraph 3.4.4.2. of Annex B8, shall be calculated separately for each dynamic segment 1 and 2 and reported. The calculation of drive trace indices during the constant speed segments shall be omitted.

              7.4.3.3. City cycle test procedure (paragraph 3.4.4.1. of Annex B8 replacing WLTC with WLTCcity)

              For the application of the drive trace index calculation, two consecutively driven city test cycles shall be considered as one cycle.
              For the city cycle during which the break-off criterion is reached as specified in paragraph 3.4.4.1.3. of Annex B8, the drive trace indices IWR and RMSSE shall not be calculated individually. Instead, depending on the number of completed city cycles before the city cycle when the break-off criterion is reached, the incomplete city cycle shall be combined with previous city cycles and shall be considered as one
