Perfect Sinastry

This is the sinastry chart between me and one of my best friends. I just find out his birthday hour after serious research and investigation. All my persuasion skills were needed. (Tickles and chocolate included), but finally I can have an accurate chart for us. And what the hell, it's extreme awesomness. I got to share:

I really love that accumulation of planets in 4th and 5th house. And our Gemini ascendant... so freackin' great!

What about you? do you have a special sinastry chart you can share? I'm just curious.

Yes, milady. The one shown above uses midpoints.

Wait, there's nothing shown above, what tha...?
Oh, well. Paste the link.

Fixed.

A composite chart shows the relationship as a whole, a sinastry chart compares two charts withouth finding middle aspects, but both explore the relationships between two particular planetarian placements, so the final result must be similar. They are just different approaches to the same thing.

Or at least that's what cafe astrology says. 😆

Ok, now I'm a messed up newbie:

A composite chart shows the nature of the relationship as a whole, while the sinastry chart shows how the different energies of each person combine. Is that correct?
