Rationale
Some characters run a mix of 4-Star and 5-Star artifacts such as 4-piece Instructors, where many units will use a 5-Star Energy Recharge timepiece to have enough Energy Recharge to Burst consistently.

Some characters run a mix of 4-Star and 5-Star artifacts such as 4-piece Instructors, where many units will use a 5-Star Energy Recharge timepiece to have enough Energy Recharge to Burst consistently.
To account for the fact that substat values are not strictly supposed to be 0.8x because you can have one 5-star artifact is to take an average based on the number of 5- and 4-Star artifacts you have and adjust the artifact stat scalar.
