Latency numbers are written with three significant digits (4.21 ms). I'm curious about the accuracy of the measurement device. If it can measure tens of microseconds, I'm impressed. If it can't, the conclusions in this article should be taken more coarsely.
> it starts collecting samples from the photodiode (every ~24 µs).
They also have repeated measurements which improves the precision.
