To be honest, “real finger-clip” sensors are similarly fuzzy in their results - after all they work the exact same way. Maybe using percentiles is not ideal as it gives a sense of more accuracy than what makes sense.

They don't work quite the same way. The finger clips shine through the entire finger. The illuminator is on one side and the sensor on the other. The wrist-based sensors rely on reflections through the skin which is a lot more iffy.
