The researchers now have an issue that is not only the bane of experimental science but also crops up in other areas such as industry.
The test is repeatable but is it
reproducible?.
Having participated in reproducibility testing along with other laboratories around the world, a problem the researchers have is that the number of laboratories that are currently able to perform this test is woefully small.
For a reproducibility test to be statistically valid, the number of laboratories participating has to be quite high.
