Sorry, that's not quite what I meant, I'd assumed you'd made a local db with this data and were using sql to pull, so I meant in terms of a sql GROUP BY expression, but no worries, I'll chuck your data in a spreadsheet really quick and update this comment with the results, which I think will be interesting
here we go:
Code
| dnd | 0.932 |
| nondnd | 0.903 |
so going strictly by review counts, they're nearly indistinguishable
