There is another possibility for the '1' and '1y1'. It may be possible that y can refer to any solid astral body. And then 1y1 would mean a large astral body, or a planet. This would still be consistent with what else we know. This would mean that wyw,zyz, could refer to any living/ non-living body instead of just planets. If this is the case then it follows that ~y~ could mean a moon. Therefore '1' can mean big without contradicting previous interpretations.
