I'm not in the EBU, but... in the first instance, a convention is an  
agreement, and a psyche is a call which is *not* made by agreement,  
so a psyche, whatever color it may be, cannot be a convention. As I  
understand it, the "red, amber, green" classifications are designed  
to deal with the question whether a call is actually a psyche, or may  
be a CPU. If there's no evidence/likelihood of a CPU, it's green, if  
there's some evidence, but not enough to rule there *was* a CPU, it's  
amber, and if it looks like there really was a CPU, it's red. In  
theory, at least, the SO tracks these things, so that a player will  
be known to have made a particular psyche, which may have been  
classified green or amber in the past, but now there is cause to rate  
the latest iteration as red, because of frequency. It is under Law  
40B that the psyche classification regulation falls.
