What should be taken into account when interpreting house profections?

So far, I haven’t found the profection years to be very accurate or impactful for me and I thought I might be interpreting them too superficially.

I am about to enter my 1st house profection with ASC in Sagittarius. Do I focus on Jupiter being in the 7th house in Gemini? Do I focus on placements I have in the 1st house, such as Pluto and Chiron?

I’m guessing Pluto predicts a transformative year. However both Chiron and Jupiter confuses me as to whether this will be a positive or negative transformation. Would Chiron and Pluto in ♐️ predict a religious/spiritual quest or predict a change in relationship with a male figure? And how would Jupiter/Gemini/7th house affect this?

Also, so far I have read my chart through Placidius, but I remember someone mentioning Whole Sign system needs to be used for profection readings. Is this accurate, and if so why? Because with Placidius, I also have a Venus 1st house.
