I recommend maximal 10 FATEs each day.
It took me 732 Fates in order to complete the event 100% and that was below average since I had people posting the in the Megathread that they were taking around 800-900 fates to complete it. There's no way to comfortably get that second whisper mount without becoming a slave to Fate grinding during this event.

Also, gonna plug my old Megathread here since all the information is still relevant: Yokai-Watch Event Megathread Guide
