1 repeat of chart A done. 90g remaining. Approx 10g used.
2 repeats. Forgot to measure.
3 repeats. 65g remaining. Approx 25g used for 2 repeats.
4 repeats. 50g remaining. Approx 15g used for 1 repeat.
5 repeats. 35g remaining. Approx 15g used for 1 repeat.
6 repeats. 20g remaining. Approx 15g used for 1 repeat.
1 repeat of chart B and bind off. 16g remaining.

I probably could have managed a 7th repeat of chart A but it would have been close and 6 repeats is large enough for me.
