What's Wrong?

significant increase in usage calculations while doing exactly the same thing. What would take about 10% if that in 5-hr limit usage, is now sitting at approx 50% usage limit. Same model (I force switched back to opus 4.6 1 million due to noticing a huge increase first) and same effort (high) actually I changed to auto, so it should decrease since I usually use high for everything. Instead my usage is showing as being more.

What Should Happen?

Usage should not be being consumed this much when I'm doing exactly the same thing I have been with the same models and the same effort and same plan
