1234 2345 1235 1234 2345 2345 5432 4321 4321 5321 4321 5321 4321This feels right to me.
The logic for going up is that I've got a 6th between 1-5 the whole time. Having a 5th is less comfortable to me.
Am I the only one who looked at this and saw all 2345 on the way up and all 5432 on the way down?
