X-Back Shrinkage, Branching Out Progress

I finally did laundry today, and got to send my swatch for X-Back through the full wash and dry cycle. I wish I had done this before I started my X-Back, b/c my calculations indicate quite a bit of expected shrinkage:

Unwashed Swatch: 3.5" x 5.5"
Washed and Dried Swatch: 3.375" x 5.3125"

% Shrinkage Lengthwise: 0.125/3.5 = 0.0357 = 3.57%
% Shrinkage Width-wise: 0.1875/5.5 = 0.0341 = 3.41%

Expected Lengthwise Shrinkage: 0.0357 * 20" = 0.714" = about 11/16 of an inch
Expected Width-wise Shrinkage: 0.1875 * 10.5" = 0.35805" = about 6/16 of an inch

Actually, the shrinkage isn't so terrible, I guess, presuming my calculations are correct.

As for my BO.. it is taking much longer than expected. There has been a lot of negative progress lately. I am at a point where I have reached a break in the yarn, and I am reluctant to continue.. Ugh. When will I finish this thing?
