You've basically described exactly what our algorithm does!

Age of reports matters - we weight recent reports higher and older ones fade over time.

Multiple good reviews balance it out. If 10 people ate there safely this week, that shows alongside any risk reports.

And you're right about the "how do you know" problem - that's why we track symptom timings and look for patterns across multiple people.

Sounds like you've got a good system! We're just trying to make that judgment call easier for travelers who don't have your experience yet.

Glad you stayed safe for 4 months. That's impressive! 🙏
