Codex Pro's credit limit was cut? A week's worth of credit was gone in just 12 hours?

This means I can't even use up the 5-hour limit three times. It means I'm using the new sub-agent feature. Previously, in version 8.7, I could never use up 20% of the weekly limit. I never even reached 70% of the 5-hour limit. How can the Pro weekly limit be used up in less than 12 hours? Is my weekly limit less than or equal to 3 * 5-hour limits?

Now I'm using another Plus plan, and I find that it consumes even slower than the Pro plan. Using the same methods, the weekly limit only decreases by an average of 2% per hour.

Please tell me what the mechanism is? Why don't I cancel the Pro plan and subscribe to two Plus plans instead?
