Losing Weight / Body Fat

My spreadsheet keeps telling me that I'm losing weight.

For the week ended (roughly) 04-01-2005 (friday), I have the following numbers:

Date / Weight / 5 day moving average
03-23 / 211.5 / 22.5 %
03-24 / 225.0 / 15.0 %
03-25 / 226.5 / 24.0 %
03-26 / 227.0 / 25.0 %
03-27 / 225.0 / 20.0 %
03-28 / 218.0 / 22.0 %
03-29 / 224.5 / 23.0 %
03-30 / 216.5 / 21.5 %
03-31 / 220.5 / 26.0 %
04-01 / 219.5 / 24.5 %

Therefore, for week ended:

219.5 pounds (loss of 50.5).
Body fat at 23.4% (loss of 11.5% in body fat).

As far as measurements:

Biceps 17.0 - 14 = 3.0 inches;
thighs: 27.5 - 24 = 3.5 inches;
Upper waist: 48.0 - 42.0 = 5.5 inches;
Lower waist: 43.0 - 39.5 = 3.5 inches;
Chest: 53.0 - 44.0 = 9.0 inches;
neck: 18.0 - 16.5 = 1.5 inches.

It's really an enormous accomplishment so far. But I feel like there's so much more to go. Perhaps it's because I was sick today and didn't get any workout in (coupled with an externship day from hell due to inattentive supervision and lackadaisacal back-up supervision).
