Maybe this is helpful to you. I created a form to post all results and gather them in a database/spreadsheet.
Usage is quite easy, data is publicly available, also some pivot tables for easy info what to find where and the respective commoness of items. You can also copy the spreadsheet and do your own analyses, if you want

If the original poster finds this useful, maybe put it in the top post. There are about 10 or 15 people posting their discoveries in the form.
