Draconic Chart - Why not count back to 6° Pisces?


[FONT=&quot]Hey all,
[FONT=&quot]I study astrology for some years now but one question that doesn't give me ease. Why is in the draconic chart counted back to 0° Aries instead of 6° Pisces? I thought that through the precession of the equinox it begins now at 6° Pisces and not 0° Aries. So don't we have to count back to 6° Pisces to get the real draconic chart?[/FONT]
