Yeah I hadn't been aware of that change previously. I'm also ET, but perhaps I just don't use it enough to hit the limits. They could definitely do to be more transparent, maybe instead of percentages, show a "credit" allocation such that the time-based variation in 5-hour windows is visible.

I am also not a heavy user, it's just so frustrating because nothing is ever defined. Something is always under one promotion or another. Abd the vagueness about weekly limits remain unchanged is they refuse to clarify whether that means tokens or number of 5hr blocks per week (that now get used faster during peak).
