Experimentally we observe quite frequently value above 2. However, please be aware that there are a lot of loopholes in our test. The most obvious ones are:
- Position of the polarizers is not random.
- The detectors are not well separated.
Other loopholes exist, but all realistically known loopholes have been closed over the course of the last three decades. \cite{Giustina_2015,Shalm_2015,Hensen_2015}.
