They're doubling the five hour limits, but no mention about the weekly limit. So overall it's the same maximum usage, right?

I think so, but that's also really great because I frequently run into the five hour caps, but very rarely use my entire weekly allotment. There are lots of situations where I do things like write the plan for all the work that has to get done, and then set a reminder to execute the plan after I get home, when I'm done making dinner (because e.g. my five hour cap ends at 6pm). Higher caps for the five hour period is a lot more convenient.

Some get the reset, some don't it seems :(
