Q: Do Precision and Opportunist stack?

[gflash]

As above, do the fortification reductions from the feats Precision (25%) and Opportunist (10%) stack?

I searched the forum and the wiki (via google) and could not find an answer.

Wiki has this:

Notice that at the end is a link to a forum discussion:

And the last post says that someone explicitly tested your question:

TL;DR: Yes, says the internet.
