I only use Claude Code, not the web UI. The window seems to start at first use, but I haven't noticed any problems with this. I tend to write "hi" to Claude first thing in the morning just to get my first 5-hour limit going, some time before I start actual work.
Occasionally the "did you try turning it off and on again" advice, so logging out and in again, seems to help with rate limiting issues.
That said, I wish they would turn the 5-hour and weekly limits into a rolling window.
The average rating (status-mood) is unclear imo. Right now it shows "Struggling (40%)" for ChatGPT and "Mid (15%)" for Claude. This suggests that ChatGPT is doing better than Claude (based on the percentage number), when actually the opposite is the case. And Gemini seems to be doing best right now, but has the same low 15% rating as Claude. I would expect the percentage to be the actual average of ratings, not how many people voted for "Mid".
