Usage metering is broken, maybe cache issue

Yeah I'm not only one saying it, we all see how fast we're burning through our limits. Just another paying customer adding to the chorus. The subreddit will stop drowning in these posts once the issue is properly addressed.

I specifically wait until after peak hours to start my work. Today I just saw ~25% of my 5-hour quota gone to a single Sonnet prompt with custom tool uses in the response. Painful, but at least caching should help going forward, or so I thought. But no, next response in that session used another 25%. Closed the app and came here.

Some of the inefficiency could be attributed to the custom tool in use, but I think prompt caching is broken.
