I can't speak to the average around this forum, where ,ost folks are past masters at pack weight reduction, but I can tell you that 27 lbs. for 7 days, omitting only water weight is FAR better than the average of all backpackers, and a pretty respectable showing altogether.

I've been backpacking close to 40 years now and my current 7 day pack weight without water would be very similar, or a couple of lbs. over yours, depending somewhat on time of year and where I was hiking. Of course, that does include everything I would carry, without any fudging, like putting my camera in my pants pocket and calling it "zero pack weight".
