Honestly, I've only ever actually hit the 5 hour limit a handful of times and it's been around 30m or less from the next window... I've either stopped for the day or took a break and continued in the next window.

I'm not running a bunch of agents in parallel as I actually review/track most of what is getting done while it's happening.. sometimes I'll stop/rollback and rerun with updated instructions. I can't imagine anyone actually doing meaningful reviews of code generated by a half dozen agents running in parallel for example/contrast.

That said, I mostly stand by my statement... at least in how I've been using AI lately.
