I'm definitely getting more than 4 hours of Astra usage (medium or high, typically). However, I predominantly use Sol or Luna because Astra simply isn't (or shouldn't be) necessary for every task.

That said, I'm not able to get anything useful done in those hours. The exception is when I swap back to 5.6 Sol/Luna, which seem to be working as they used to.

Mostly, I've just given up and am using Opus 5.5 for all the important tasks now. Which is odd for me say, because I cancelled my Anthropic sub a few months back because I couldn't stand Opus 4.6 < x < 5.5. 5.5 feels great though, like Astra did when it first released.
