Sometimes the most important discoveries happen due to serendipity - knowing what was used where is the most important thing when understanding outcomes.

The reactor was designed and its manufacturing could be controlled - however, many researchers across the world rely on their material suppliers to NOT be lying about, or mis-representing what they supply. 'Professional' organisations can be victim of this also.

With around a million dollars spent on developing ECCO, it is extremely cheap by standards in the field, so on that measure it could be considered amateur, however, it is still a lot of money and the outcome is what is important.

The material supplier, who apparently is quite respected, has been the unprofessional party in this.
