Limesurvey
Best practices
Readibility To increase the readability for the respondent restrict the number of questions per page so that the user doesn't have to scroll to see all the questions.
Also, due to technical reasons the maximum amount of data that can be transmitted to the server is limited.
The maximum number of questions on each page depends on the question type used ( open fields, for example, use more resources than questions with radio buttons) and the browser on the client side.
Pilotstudy In order to reveal hidden problems in advance you should plan a pilot study before you deploy your survey. 
Also export the data from LimeSurvey into SPSS to check if the data structure (type and variable names) correspond to your research requirements.
Browser Although Limesurvey works on all modern desktop browsers, it is recommended to use a recent version of the Mozilla Firefox browser for designing your questionnaires. Try where possible to recommend it also to the respondent. Click here to install or update Firefox

Survey behaviour
Present a stimulus for a fixed period of time and auto-advance Example (time: 3 seconds) https://limefppw.ugent.be/limesurvey205/index.php/481325/lang-en

How do I repeat a survey using the same token Increase the "Uses left" in the token list and reset the "Completed?" field to "N". You can optionally import a CSV file with a token list.
Tip You can ensure that a participant can resume a survey without the procedure with email and password, by enabling the setting "Saving Enable persistent responses based on access codes?"
