Resolved! VL53L4CD Calibration - Measurement Timing Budget

Hello ! I am calibrating a VL53L4CD ToF sensor. Is it suggested to set a large timing budget (e.g. 200 ms) for the offset and crosstalk calibrations' distance measurement process? In the distance measurement examples, the timing budget is set to 10 m...
