Anchor Text Percentage

I'm trying to rank a keyword for a inner page that has 11% exact match for my anchor. Is that too high? I was thinking about using the exact match keyword for a PBN post. What should I use to get that keyword bumped up from #9? Thanks

Make 50% url links since kw is on domain and other 10% make it generic, 25% make it brand links, 10% niche related links and the other 5% make it exact kw that should do it.
