I like form analytics, but I would like to have the option to measure according to my form needs, for example, I have forms with the option just to be filled by 40 users, which I have the names predetermined, not error misspell.SAying that I would like to measure the performance o every user, how can I do it????

Unfortunately, we do not have an option to do that in the Form Analytics page. 

You can try the Quiz app to show the score or performance results after filling out the form. Here's a guide: https://www.jotform.com/help/289-Turn-Your-Form-into-a-Quiz-or-Exam-
