WAF Threat Score Range for the Rules

Hello,
I have just registered my website with Cloudflare and Creating rule from Security → WAF → Create Rule I need to understand the Threat Score range for for low & high level of threat.
With reference to the following article from documentation,

Rules Set Engine => Field Reference
It says “0 indicates low risk. Values above 10 may represent spammers or bots”.

However another article of WAF

It says * A score of 1 indicates that the request is almost certainly malicious.

  • A score of 99 indicates that the request is likely clean.

Can you please guide to apply the proper rule for threat score.
Thank you In Advance

Regards,
