172.68g to start. 65% is 112.24g. After three large stripes, 123.58g left.

Starting section 2 with 113.69g left.

27.28 — measuring rows with a few rows left. 26g after two rows. 24.39 after two rows more. 3.11g in four rows, 1.55g per pair of rows. 22.72 after three pairs of rows. 1.52g/pair. 15 rows to reduce.

.78 grams left after bindoff. I had to reduce one stitch extra close to the end to avoid running out of yarn. Using closer to 34% on Section A would have been more accurate.
