[BUG] Claude Max token quotas are badly broken

What's Wrong?

This morning, I burned through my entire Claude Max 5x quota in an hour, using the same workflows and task volume with Opus 4.6 that used to last for 5 hours.

This afternoon, I burned through the same quote in two hours using Sonnet 4.6, which would've lasted me all week previously.

What is going on, Anthropic? I'm this close to canceling my subscription after being a faithful customer for well over a year. Your product used to deliver great value... and now it's feeling mighty overpriced.

What Should Happen?

I shouldn't be burning through my entire Claude Max 5x quota at 5x the speed when nothing has changed in terms of my usage patterns. And Sonnet 4.6 shouldn't be nearly as costly as Opus 4.6.
