i tried the game today and i feel it is very inaccurate... for its weight it said i was 86 pounds and that im underweight when in i only weight 126.i am 15 years old and trust me,thats a WIDE gap for weight.... i tried it a second time, and it the results were the same... so what the heck??? is it my balance board, or what... oh and does it matter if its on carpet to get more accurate results or no???
