Why not ask the person who organises the rankings directly?
As far as I know there have always been (in the last 20 years) rankings for the 2 main bowstyles and no others (compound appearing in 1995 I think) perhaps because there's too few people shooting other bowstyles to make a ranking worthwhile? Or perhaps because one of the purposes of ranking was for team selection... i.e. compound and recurve only
Lets face it, in some years we're just about managing enough ladies compounds!
Maybe if you asked they would do a ladies barebow ranking with just you on it
