Dear Dyane,
Many thanks for your kind words and encouragement. This is what makes the Top Synergy project worth its while.
Indeed we normally use the Placidus house system for both the astrological profiles and compatibility (synastry) reports. However, we can as easily calculate your chart with ANY other house system, including Porphyry, or better yet - we can use Geodetic calculations with Porphyry intermediate cusps. You can also specify in your donation what type of coordinate system to use if the normal one doesn't match your requirements.
"Ratings" on the Relationships Analyst report are a derivation from calculating numerous aspects between plants, houses, and signs in each person's chart and between the two charts. The 0-to-5 scores are a populist mean to express far more complex data in its raw format.
The difference between score of ONE, THREE or FIVE should be regarded subjectively and viewed according to a given situation.
The score of ONE already shows cosmic energies in presence and intensity that are substantial and greater than the average. Difference in scores could be meaningful on two occasions:
1. Major gap between the scores of each party, i.e. one scores "0" passion while the other scores "5". While usually the mutual score in such case will be greater than zero, it still demonstrates an imbalanced situation that might need to be addressed sooner or later during the lifetime of this relationship.
2. A relationship that evolves in stressful situations, catastrophes, and hardships can use a greater than ONE score in its commitment department
Thanks for the opportunity to address these interesting topics. I hope that all your questions have been answered in full.
