Regarding critical damage with the revamp

The rate from skills stacks with the 5% base rate.

 Slinger with Max Critical Shot

Can you take a sample of your damage really quick please? Just head to snails or whatever has negligible defense now and shoot like 50 double shots, noting down your highest critical, highest noncritcal, lowest critical, and lowest noncritical. It'd help a lot for figuring out how criticals work :o

Also, I noticed that your mastery is 65%. Does it say anywhere where that extra 5% mastery is coming from, like on your gun? Or is the base mastery just 15% now?
