Yes, I didn't think of that, would clearly cause problems too.
Tangentially: I know such methods* don't produce extents in general, but are there specific cases where they can? I can't see a reason they shouldn't if you allow singles and have a carefully crafted method, but I am not aware of any examples.
*I should probably define which such methods I'm talking about for the avoidance of doubt/avoidance of dozens of messages attempting to clear it up. I'm interested in treble dodging (single dodges) minor methods with palindromic symmetry in which one or more treble positions appear twice + or twice - in each half lead. As exemplified by Kelvinbridge S Minor. (5 leads to the plain course would be nice, but not really necessary.)
