Sensor data with highest frequency

I recently discovered, by using the new Input System, that the device reports high frequency data (got around 150 Hz in editor).

This data includes deviceposition & devicerotation, but also devicevelocity, deviceangularvelocity, deviceacceleration, deviceangularacceleration.

1. Are the velocity and acceleration derived from position and rotation? Is it the raw data from the IMU?
2. As a follow-up, if I integrate the acceleration twice - would I get the position? Or is there any discrepancy?
