VL53L1 calibration using water target surface

Hello again!
I've been trying to measure water level using the VL53L1 sensor and reading forum posts on it, and I've gathered that RefSPAD calibration isn't really recommended anymore.

From my research on the topic, I know that water reflects only 2% of perpendicular incident light, with the rest getting transmitted and also that the transmitted rays will be fully absorbed at a minimum water level of 10cm.
I was wondering if doing the RefSPAD calibration utilizing the VL53L1 (with a cover glass) leveled parallel to a water suface from a body deep enough to absorb all transmitted laser could end up improving the sensor's results by giving more weight to SPADs more likely to detect those perfectly reflected photons.
Thanks in advance!
