Also, I on the 1930's Swap, I followed a D4P tutorial by MSQC. Does following that tutorial produce the same block as the tutorial on this swap? On the MSQC tutorial, the larger outer blocks are flip-flopped across, and the small middle square is rotated by one turn to the left. The narrow strips are never moved.
This is different than the tutorial for this swap which says to just flip the narrow strips.
Just curious.
