VL53L0X offset/xtalk after temperature calibration

Hello, I have a question about the temperature calibration for the VL53L0X Time-of-Flight sensor.

The UM2039 manual states the following:
> [Temperature calibration] has only to be done before offset and cross-talk calibrations, after Reference SPADs  management and before the first ranging is performed.

During assembly of our product, those calibration steps (SPADs, Temperature, Offset, XTalk) are performed in order.

To account for possible temperature changes when the device is in use, we call both  `VL53L0X_PerformRefSPADManagement` and `VL53L0X_PerformRefCalibration` on device boot to ensure the sensor is ready for use for the current temperature.

My question is if this would affect the offset and xtalk calibrations, since the docs state that temperature calibration must be perfomed before those. Or is that sequence merely to ensure the offset and xtalk calibrations are done with the correct temperature calibration.

Thank you for your time.
