Hello Bryan,
I do not have the data for the configuration you are mentioning.
But with my Fox 245 Multi Vtech loaded at 0.75 lb/ft² and with a 28" PC (I was skydiving with my Fox :7 ), having my eTrex Vista attached to my helmet, downloaded data into my PC and plotted the vertical/horizontal plot bla bla bla and so on and so on and so on, I got for glide ratio an average of 2.20 (taking for the average everything, both data where I was flying downwind and data where I was flying upwind).
So, when I need to consider flight distance in my BASE jumps, I conservatively consider to have a canopy whose efficiency (glide ratio if you prefer) is 2.00. That is to say: for every single meter I go down, I go forward 2 m.
I hope it helps!!!
Stay safe out there
