>The timeboxing of planning is also a very bad idea. I worked at a place where we had a timebox of 2 hours for planning but really after that we were nowhere near a realistic plan for the sprint and it would take another 2 or 3 days of knock-down, drag-out meetings that would leave us all exhausted to understand what we had to do. After that the work was mostly downhill, at least the way I saw it, but one of the other team members would consistently burn the midnight oil at the end.

If your backlog is properly groomed and you have sufficient time for planning and the team has the last word on how much it tries to take in, then it works beautifully.

If my team was to have that problem, it would come up during the retro, we would add a few more hours for the planning event, hold more or longer grooming sessions, refuse to plan work which we can not yet estimate because the requirements are not clear, etc.

And btw, your "implementation of Scrum" wasn't working properly; probably because you weren't living up to the Agile principles.
