But, conversely, gaining back those 20 lbs would not result in higher wattage. So, your W/kg is maximized when you're lean. So, when someone like Dr Coggan says "the ceiling for an average Joe is 4 W/kg", he means that the ceiling in terms of absolute wattage is 4 x lean weight, not 4 x actual weight.
