OK so if I use upright sprinklers, since there is not a listed residential upright (that I am aware of) do I do a 2 head calculation at .05 over the coverage area or .10 using QR upright sprinklers? I guess my trepidation comes from the fact that this is a large open area, it doesn't really have the compartmentalization that is typical of a 13D system. 2 heads just doesn't seem adequate, but that's just me.

Yes, you do it per 13d. Also check out the 2012 version of the irc, section p2904.
