I’m looking for a subreddit where Japanese users share or discuss learning English through anime, especially sports anime like Haikyuu.
I'm developing a volleyball match analysis app (yes, I'm the developer — also a volleyball parent who started tracking my kid's games obsessively).
I'm working on adding CSV export, and I want to make sure the data is actually useful — not just a dump of numbers nobody needs.
So I'm curious: do any of you export stats and dig into them in Excel or Google Sheets? If so, what are the columns or metrics you actually find valuable? What's missing from most tools?
Brutal honesty appreciated.
