Body Fat Calipers - Day 3

I've used body fat calipers for 3 days now. . . and I've come up with the following numbers for body fat.

23.17%
24.47%
24.81%

THese numbers are quite similar (though not exact) to my Tanita body fat scale (which seems to think I'm ~19.5-22.0% depending on the day. It surely seems that using calipers has a lower problem with precision -- what I measure one day, seems to be pretty close to my result two days later.

One of the websites recommended that you take your body fat via calipers every day for a week. When you come up with consistent numbers, then you've refined your technique. The refined technique means you have reliability (a reproducible result) -- then again, though the result is reproducible it doesn't necessarily mean it is accurate. It could be high/low by a few points due to my own application of the technology -- but, i suppose the point is, at least it will allow me to judge the trend.

The rough math seems to be this: I weigh 230 pounds; if I am 25% body fat, and I wanted to reduce to bare minimum (5%) -- then I could drop 20% to become completely lean: 20% * 230 = 46 pounds. or roughly 180 pounds. That doesn't seem right at all to me though.

Erg / Concept2

I got back on the erg tonight for 20 mins (3200 M) -- I only did it to test my back. My back still feels a bit strained while on the erg so I'll probably take a few more days off of it and stick with the cycling (I'm in the midst of finals so exercise will be sporadic at best).

NUTRITION

My nutrition seems to be better. I've always worried about nutrition during finals because it is my most stressed out period and I tend to eat more. Perhaps I'm managing stress better -- but the much more likely reason is that I'm not as stressed this finals go round. Thankfully the madness will be done soon -- I know it's just a matter of hanging on for the remainder of the ride :-).
