Wow, weird to see someone mirror my experience so closely. At the $100 plan my day was being warped around how to maximise multple 5 hour sessions so that it felt worth it. Dropped down to the $20 plan and stopped playing the game as I know I'll just consume the weekly usage in the few days I have free. Meanwhile codex gave me a free month, their 5HourUsageWindow:WeeklyUsageWindow ratio feels way better balanced and it gets may more work done from it. Similar to you, any task involving reading/reviewing docs [or code reviews] now insta-nukes claude's usage. My record is 12 minutes so far...
