I'm not making an assumption about anything. A clutch of normal 33% possible het pieds is
worth as much as a clutch of normals in today's market. A knowledgeable person wouldn't even advertise them as such. I understand that a het can produce a het, but I'm not going to sugar coat a possible het x normal pairing to be more than it is.
It is worth significantly more in experience value if you want to count that.
