What's Wrong?

I'm experiencing what appears to be a bug with Opus usage limit tracking on my Max 20X plan when using Claude Code. The weekly limit is being reached within hours instead of the expected 24-40 hours per week.
Timeline:

Last week: Hit limit after a few days of normal usage with message "Opus weekly limit reached ∙ resets Oct 24"
October 24, 2025: Limit reset as indicated
Today: October 25, 2025: Hit limit again within ~1 day with message "Opus weekly limit reached ∙ resets Oct 31, 9am"

This issue started appearing last week. Prior to that, I never encountered this limit despite daily usage of Claude Code for development work since subscribing on May 24, 2025.

What Should Happen?

According to the official documentation, Max 20X plan should provide 24-40 hours of Opus per week.
The limit should only be reached after accumulating 24+ hours of actual Opus usage within the weekly period, not within a single day.

Error Messages/Logs

Opus weekly limit reached ∙ resets Oct 31, 9am

Steps to Reproduce

Use Claude Code with Max 20X plan subscription
Select Opus model for code development tasks
Use normally throughout the day (significantly less than 24 hours)
Observe limit being reached prematurely

Note: This issue appears to affect usage tracking/metering rather than being reproducible through specific commands or workflows.
