How would I know the day it starts?
- Feder reads the form submissions Jotform records each day and compares each day with your own history.
- It does not tell a real submission from spam.
- It tells you when submissions go quiet or move outside your usual range, including a sudden jump.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See what Feder reads from Jotform, which feeds Interest. Feder only reads. It never changes anything in Jotform.
