In the Homestretch with the Series of BFL Skeins

I am in the homestretch with the series of Blue Face Leicester skeins I'm spinning.

I finally got that underplied skein plied again to correct the twist.

I'm partway through spinning the final skein.

All the skeins are supposed to be one ounce. I started with eight ounces of BFL, used a scale to divide the fibre, and somehow wound up with half an ounce leftover. Does this mean the skeins are not, in fact, all exactly one ounce? I will never know, since I've already given the first four skeins to the intended recipient. I have a sneaking suspicion that most of the discrepancy happened with the first skein since it has considerably longer yardage than the others.

I'm pretty happy with how similar in yardage the others were. I was aiming to develop my skill at making a consistent product. It may be that consistency is the hobgoblin of small minds, but consistency is a good quality in handspun.
