This is just pure speculation. However, I have two key insights:
1) People have typed her Inventor by comparing her with Ayn Rand. While Rick DeLong typed Rand as ILE, the modern consensus is that Rand is a completely different type... Some type her as "Gamma Extravert" while to others she is "Beta ST"; rarely is Rand typed as ILE.
2) In some pictures, Augusta VI's differently from Inventor. E.g.:
What could be going on here? Are the pictures not accurate? Is there something wrong with VI? Could the typing system have changed over the years, such that she would become a different type under a different system? I realize that this is just food for thought, but I would be interested to hear anyone's opinion...
