Eric's Heidelberg Psi Index

When Eric Olafson had his Heidelberg PSI Index tested, it measured only 34. That was considered normal for Nilfeheim, a planet where everyone had an tested HPI of 50 or less

Due to an incident in his first year of academy training as well as some later ones, it's speculated that his HPI is now higher than it originally was, although it's not known by how much it has increased.

While in some specific cases an individual may have their HPI retested, unless it's related to a criminal investigation, the individual would specifically need to request it.
