I made it to 27.25 inches this morning, which is .75 inches short. This is especially annoying since I was at 1.5 inches ahead of my goal yesterday. On the other hand, I only had an hour to knit for today's total, so at least I'm keeping up a fairly good pace.
I think an inch is about 8 rows - which is 480 stitches. So, 2,280 stitches in an hour. Which sounds impressive but comes out to 38 stitches per minute. A little slower than my very-fastest garter stitch before this all started.
Actually, I'm completely happy with that pace, when you consider that I'm working cables every 4th row.
For those cables, I'm using the look-ma-no-cable-needle method of just dropping the four stitches off the needle, re-arranging them, then knitting them. It's working really well.
