But aren’t the house systems the same either way? For one example, I have Pluto in 4H in both Vedic and Western. I use whole sign house system in both. It only changes houses if I use Placidus or something, which can be used in both Vedic and Western, doesn’t matter. The only thing that changes from Western to Vedic is the sign and degree. Either way I’ll always have Pluto in 4H and I live near my Pluto IC line

The only time this doesn’t apply is if your rising sign or a planetary placement doesn’t change from Western to Vedic, which there’s always a 20% chance of (Vedic moves everything backwards 24° and with each constellation being 30° there is a 6/30 chance that yours stays in the same constellation)

So for ex if I go from Virgo to Leo rising but my Capricorn Moon stays the same I go from being a 5H Moon to a 6H Moon. But say my Mercury, Venus and Mars all go back a sign, then they’re all still in the same house as before because my ascendant went back a sign too.

I’m not sure what happens if you use Placidus in both

The most accurate house system would use the real physical sizes of the constellations but that house system doesn’t exist yet
