I'm sorry, you don't break the laws of science. That would be 1200 calories of fat 3 times a week. According to various sites you'd burn 279-558 in an hour, depending on your pace. Compared to running which is 930-1400.
And a pound of muscle at rest only burns 6 calories per day vs 2 for fat.
Body fat % calculations are not always accurate, also.
one of the reasons that weight training is effective for weight loss is that, unlike cardio, you continue to burn calories at an elevated rate for up to 36 hours after leaving the gym.
the reason you are burning calories at an elevated rate is that weight lifting creates microtears in your muscle fibers and your body burns calories to repair those tears.
you don't build muscle in the gym, you build it outside the gym. in the gym you are breaking your muscles down and creating those micro tears that promote hypertrophy.
as far as body fat calculations being accurate, i completely agree, they are not 100% accurate.
but tightening my belt by 3 notches tells me that it is close enough.
(you also forgot the extra calories it takes to actually build the muscle ... i have no idea what that cost is in terms of calories and protein)
