The different operating TOF modes (for the TOF V2 sensor on Starling 2) are described here in terms of power usage and fps : https://docs.modalai.com/M0178/#irs2975-operating-modes . We do not have exact information, but the different modes emit different amount of IR power and using different modulation schemes. The operating modes are tuned for the different ranges as stated (ultra short, short, mid long), which means depending on your application, you can choose one or the other.
The number of sampling points per frame is the same for each mode, but FPS can be chosen based on what you need and it has to be within the provided specs (short range allows you to use higher fps).
We have not done specific studies to measure the performance of the sensor to the detail that you are asking about.
I can collect some data for you if you need. What format? There are also some tuning parameters, that can be tuned (can be found here with some comments : https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/blob/master/src/tof_interface.cpp?ref_type=heads#L1033) . You would probably need to experiment yourself if you wanted to get the best performance out of the sensor.
