A e2e post wrote that the accuracy of ALS is 10%. Does 10% mean the accuracy between sample to sample (For example, when the ambient light is 2000lux, sample A outputs 1800lux, sample B outputs 2000lux, sample B outputs 1900lux...). Or 10% means the accuracy in just one sample (for example, when the anbient light is 2000lux, the output value of ALS will change between 1800 and 2200lux with the time going on?
