Ya man I agree. 21% is pretty high for what your pics looked like. Is this one of those electronic measurement things? I don't trust anything but the good old caliper test.

iirc this is above and beyond the ole caliper method.

Yep. I wish it wasn't so damn accurate.

Incline bench - 165X3, 185X2, 195X1, 205X1
Dips - 3X5 + 60lbs
OH press contraption - doubles with what felt like 130, 160, and 160

The most I've ever pressed on incline bench is 10lbs less than my 1RM on flat bench. Kind of weird.

Thats alot of weight for incline! Nice work.

Do you know how this fat test works? I'm interested.

DEXA (Dual Energy X-ray Absorptiometry) - A relatively new technology that is very accurate and precise, DEXA is based on a three-compartment model that divides the body into total body mineral, fat-free soft (lean) mass, and fat tissue mass. This technique is based on the assumption that bone mineral content is directly proportional to the amount of photon energy absorbed by the bone being studied.

DEXA uses a whole body scanner that has two low dose x-rays at different sources that read bone and soft tissue mass simultaneously. The sources are mounted beneath a table with a detector overhead. The scanner passes across a person's reclining body with data collected at 0.5 cm intervals. A scan takes between 10-20 minutes. It is safe and noninvasive with little burden to the individual, although a person must lie still throughout the procedure.

DEXA is fast becoming the new "gold standard" because it provides a higher degree of precision in only one measurement and has the ability to show exactly where fat is distributed throughout the body. It is very reliable and its results extremely repeatable; in addition, the method is safe and presents little burden to the subject. Although this method is not as accurate in measuring the extremely obese and the cost of equipment is high, DEXA is quickly moving from the laboratory setting into clinical studies.

The DEXA looks like this:

That's a fairly decent explanation. I just got a scanner this week. I'll scan my printout/results and post it later today.
