Notes
This is the number of symbols correctly matched to digits by the participant.
Note that it would be possible to get a high score here simply by repeated entering "1" very quickly as it would be correct 1/8 of the time and a large number of attempts could be made. For this reason, the score must be interpreted alongside Field 6774 which shows the total number of attempts.
