Something sounds way off here. If you had this done at 274 lbs and you are trying to get to 190, this sure doesn't sound right.

When you had the bf test you were 84 lbs over your ideal weight. This was 50% above your ideal weight at that time. I can guarantee you that someone who is 50% above their ideal weight does not have 24% body fat. It would be much higher.

I suspect that first reading was wrong and quite possibly the second one too.
