A couple years ago I dropped from 19.7% to right around 5%...of course these measurements were taken with a calipher (by the same technician) over the course of several months. As most people know the calipher method isn't the most accurate...so plus or minus a little in the upper and bottom number. Nevertheless, I still dropped about 40 pounds of fat.
It is all a matter of getting yourself into a caloric deficit. If you are eating heavy calories right now I wouldn't advise any drastic drops. Start slow and shave calories off every week. Keep your protein high(at least 1.5 grams per lb. of bodyweight) and work out a good macronutrient profile for your carbs and fats to fit in as well. Then it's a matter of staying consistent when choosing a weight regimen and aerobic routine. Personally, I lift heavy with low reps while bulking or cutting...the only difference is while bulking I don't do any cardio. I add cardio only during a cut. Last time I cut I think I overdid it with my aerobics...so next time I cut I am sticking with a decent pace of walking a couple times a day. It has been shown that walking is fine for cutting up as long as your calories are on track. If you start getting too intense with your areobics you will start burning too much muscle tissue. I also have to watch my areobics when in a caloric deficit phase because my job is very physical...and I will overtrain like that { a snap of the fingers}. These are just basic guidelines, but you really have to find what works best for your body through trial and error....best of luck to you.
