Awg Wires on pages 76, 77

Hello everybody,

I see on that on pages 76 and 77 of the AR3 Robot Manual that you have to cut 12 22 awg wires and put them in a bundle, and solder 18 awg wire on that bundle. This is probably right but to me it felt like it might be the other way around (twelve 18 awg wires and one 22 awg wire), so I just wanted to make sure that's the way and I'm not overthinking it. Also, I was wondering the flexibility on the wires? For example does it need to be exactly 22, or can it also be 20 or 24. Thanks in advance to whoever answers this.
