HRV false peaks in measurements

HRV false peaks in the measurements, the apple watch performs HRV measurements, but although 97% of the measurements are in accordance with reality, there are some peaks that do not follow the trend of, so in one night I can have values of min60 and max 190ms. These false peaks should be easy to eliminate with an algorithm or am I wrong, so why don't they do it. when it comes to tracking this makes it very difficult to have an average of your hrv while sleeping or during the day.
