There currently are 70 attributes available.
You find a "table" of them within the bottom of your https://project-gc.com/Statistics/ProfileStats
The BadgeGen shows (with mouse over the Attribute Badge) that you need two more Attributes for the next loop (which will be your 2nd loop)
So you need more cross country skis and snowshoes attributes as you have only found 1 (see Profile stats). You are safe with negative attributes until loop 4.
There is no special tool/statistic. But with some clicks you get the information. And with "custom filters" and map compare you can find caches with the needed attributes in your area.
