Except that we don’t use the 29.5 days synodic cycle in Human Design, but the 27.3 days tropical cycle.

And Mercury and Venus are off too, the mistake is around the Wheel (Earth) vs around the Sun
The Planets – Ra Uru Hu – Introduction
The planets play a key role in the design of who we are. In fact, everything is based on the movements and impact of the planetary spheres.
The key to understanding the impact of something as distant as a planet on our lives is a tiny, subatomic particle known as the neutrino. Neutrinos are extremely fine matter produced by the nuclear reactions within stars. All the stars, including our own Sun, are producing neutrinos all the time. The stars out in space are constantly beaming these neutrinos at us, and being made of such fine substance, the neutrinos can pass through our bodies, as well as the body of the Earth. Imagine then, how the movements of the planets around our Sun refract the neutrino information as it passes into us.
Planets vary greatly in density and makeup. Some consist of solid rock, whilst others consist purely of layers of gases. Every planet also has its own mythology as perceived by man. Our mythologies are, and always have been, our method of attuning to our greater body.
The planets are our local programming agents. This is why we have always seen them as the gods in our mythologies down the ages. Every planet lends its flavor to our nature.
Sun – Our Light – Yang
Here on Earth, scientists have estimated that 70% of the neutrinos that pass through the Earth come from our Sun. The remainder comes from either Jupiter or the stars in deep space. Thus, 70% of all the neutrino information that we receive is seen in the position of our Sun and Earth. The Sun represents the primary yang force of our nature. It is the archetype of the Father, just as the Earth is the Mother. The Sun and Earth are the prime yin/yang within us all. The Sun creates the electromagnetic field of the solar cell in which we live. The design Sun represents the bio-genetic themes inherited from our father. If you look at your own design Sun, you will see the theme that you have inherited from your father. The personality Sun is the window through which the very light of who we are shines out on the world.
“I am involved with in a long term project which is called ‘The Global Incarnation Index’ and it has to do with our incarnating crosses that we come in on. The 27th hexagram is part of a cross that is called the cross of The Unexpected and the 27.4 is one of the great classic lines of the unexpected. Many years ago, Martin Grassinger mode some charts for me of the discovery of Pluto, Uranus and Neptune. In all those cases, the Nodes were in 27.4 and 28.4. When the comet ‘Shoemaker Levy’ banged into Jupiter, the Nodes were in 27.4/28.4.” -Ra Uru Hu, The Rave I-Ching Line Companion 2002
“Years ago in Germany, Ra was doing some research on the time of discovery of various planets. For example, when exactly did Hershel discover Uranus in 1781? The discovery of Pluto, Neptune, and Uranus – each of those three discoveries happened while the Sun was in the Cross of the Unexpected. Furthermore, when Schumacher-Levy, this incredible comet, smacked Jupiter; it happened on the Cross of the Unexpected. So there is something very unique in the way in which this cross works, because you can see it at the macrocosmic level.” -Ra Uru Hu, The Global Incarnation Index 2001
