Table 6

Results for the comparison between manual and automatic recording of time event variables. The table counts the number of correct, wrong, and missing values. An automatic recording is considered correct if the deviation from the manual recording is less than or equal to one second. Otherwise the recording is considered wrong. A recording is considered missing if the code 66 : 66 : 66, 88 : 88 : 88, 99 : 99 : 99 is used for either of the recordings or the manual recording was changed to 00 : 00 : 00 or 12 : 00 : 00.
