Multizone sensor calibration buffer

Dear forum,

I try to understand the bin shape of the VL53L8CX / CH sensor calibration buffer while evaluating different sensor cover and their influence on ranging. Using the example8 file from the ULD driver the shape looks more or less always the same (as eg. shown by @John E KVAM ) for most cover glasses I used. Nevertheless doing the math with a bin size of 3.75 cm the light path must be in range of ~40 cm, which seems to me highly unlikely with a 1 mm cover glass placed in 0.5 mm distance. Moreover I realized that the calibration buffer yields 144 bins whereas I read somewhere here that there are only 128 bins for ranging.

Perhaps someone can elaborate on that a little bit.

Thanks!
