In a survey, I forgot to include a timer for one question. As I have timers for all other questions, I thought that the difference between Q_TotalDuration and the sum of all Page.Submit variables should yield the response time for the one question I forgot to time. The results are credible values for most responses. However, in 9 out of 60 cases I get negative values. Can anyone help me explain this?
Cheers,
Niklas
