Is it 10-20% of "your users" or 10-20% of the world but <1% of "your users"

I don't follow. Assuming that the caniuse data is also representative of your users (a big assumption), then it's 10-20% of either group. Adjusting the % for the subset that is "your users" can result in either a higher or lower %.

Let me know if I'm missing something.
