It is nearly impossible to do a real-world sort of positions 5-20 in semifinals because not everyone competed against each other. But I know there are a variety of designs out there to make those distinctions.
If I were applying for grants and I was on the finals stage, I'd say what position I came in.
If I were in semis and came in second in my bout, I'd claim tied for 5th. If I was third in semis, I'd claim tied for 9th. Fourth in semis would be tied for 13th and fifth place would be tied for 17th.
Or I'd say "semi-finalist" and let the granting agency assume that meant 3rd or 4th.
But yes, the data is coming. As soon as I get some other things taken care of.
