One major difference is that our calculate it at various times as a chart based recorded weight and measurmenets. So if you suspect the numbers are wrong, double check the values you eneted for each date, weight and measurements, including height in the options/settings.
Here's the formula used:
body fat (female) = 495 / ( 1.29579 - 0.35004 * (log (waist + hips - neck , 10) ) + 0.22100 * (log (height, 10) ) ) - 450
body fat (male) = 495 / ( 1.0324 - .19077 * (log (waist - neck , 10 ) ) + .15456 * (log (height, 10) ) ) - 450
Finally, the difference between the 2 charts is that the first showes percentages (body fat ratio), the second showes the actual weight (lean body mass)
