ADIS 16507-2 IMU gyroscope bias repeatability

In ADIS 16507-2 IMU data sheet I can find for Gyroscope Bias Repeatability the following definition :

Bias repeatability provides an estimate for long-term drift in the bias, as observed during 500 hours of high temperature operating life (HTOL) at 105°C

My question is : does it correspond to turn to turn on bias repeatability ?  It seems that this is not the case.

Thank you.
