Sorry, no. Creating a search-based PIM over old backups seems a doable thing. But for now, hmm, youtube has a "before:2015" syntax..., but still, "teaching estimation" or "estimating jellybeans" or blocks, or etc. And some education sites used to self host videos. :/
It wasn't anything singular. Telegraphing/hinting at the desired response. Questions series amenable to surface pattern matching, rather than scaffolding or probing understanding. Coaching for response rather than for understanding. Lack of clarity on why estimate, and how.
Except for that last... I imagine having a film crew hovering was not low stress, especially when things weren't going well. And at the time, when early-primary estimation was still a newish thing, having even a crufty idea what it could look like might still be worthwhile training-wise. Hopefully similar work would now be better?
