Master Marksman for MM hunter is way over estimated

When I do a sim of my hunter it shows that as being close to 10% of my damage. But according to my meter its more like 3%. Makes it hard to get a good estimate of how much I should be able to do. Also MoCs only does 3-4% so 10% would be way too good. Is this a known bug?

Could you post a link to your simulation?

I see the problem, we’ll post up a fix.
