Sorry to dissappoint deron but due to launch angles and spin rates, you cannot equate a swing speed with drive length. My normal swing speed (about 80% of max) is around 110-115 and I AVERAGE about 280 or so here on the coast and better than 300 when I travel to the midwest (due to roll and added carry). One of my cohorts is about 120-130 on the speed monitor and hits it the same distance I do because he hits it much higher with more spin. Our Head Professional has a swing speed slightly lower than mine but hits a lower screamer that actually rolls here on the island (if I could figure that out, I'd be a genius) but ends up the same distance as our Director of Golf and myself. Swing speed alone doesn't indicate distance.

As for my average weekend golfer, 80-85 mph is probably a little GENEROUS for his swing speed.
