Of course, as soon as I posted I think I may have found a solution by figuring out an article I read on using the RANK function. It was pretty easy once I figured out where to put it.
Create the following calculation and compute is across the table.
Next, drag that pill to my columns shelf and make sure to remove it from the marks shelf so it doesn't show as a label on the bar chart.
That was it. No IN/OUT set necessary it appears and my percentages stay percentages of totals, not of what is filtered in the top 5.
I hope this helps someone else out because I spent way too much time looking for the answer that seems to be this simple.
